Strange Fatal Error
« on: October 08, 2016, 08:10:11 pm »
Hello,

So I've been trying to develop a new app, though I have just one major issue with it...

Code: [Select]
10-08 17:52:19.684: W/google-breakpad(18652): ### ### ### ### ### ### ### ### ### ### ### ### ###
10-08 17:52:19.684: W/google-breakpad(18652): Chrome build fingerprint:
10-08 17:52:19.684: W/google-breakpad(18652): 3.8
10-08 17:52:19.684: W/google-breakpad(18652): 16
10-08 17:52:19.684: W/google-breakpad(18652): ### ### ### ### ### ### ### ### ### ### ### ### ###
10-08 17:52:19.684: A/libc(18652): Fatal signal 11 (SIGSEGV), code 2, fault addr 0x749c3000 in tid 21230 (GLThread 3696)

So the app starts fine and the camera basically starts facing in the direction of the sunlight.
However, whenever I turn the camera (using touch or autorotation) towards the sun, the app simply just crashes However, it will not always crash...
So I tried using less objects and lower resolution textures.
Both seemed to have a small impact on the chance of this crash to happen.
However, disabling jPCT's LensFlare in my app seemed to fix the whole problem.
But, disabling most objects (and prevent their textures from being loaded) seemed to fix the problem as well.
Having both enabled just does not always work. (Maybe it will work 1 in 10 times, and once it does work, it won't crash when you look away from the sun and back)

EDIT: Nevermind, the crash can also happen with the LensFlare disabled...

Can you post there complete log or is this all there is? Looks like a driver issue at first glance. On which device does this happen?

This is the complete error log I'm getting...
Even if I enable to log OpenGL Traces in Developer Options, it doesn't give me anything else than that.
I'm getting this error on the ZTE Axon 7.
However, I remember having the exact same issue with my previous device: HTC Desire 826.

I'll post bigger logs in the next posts.

And there is nothing else after that fatal signal.

For some reason, relaunching the rendering activity after crashes seems to increase chances that the app will work.
But when you force close the app and launch the rendering activity, the chances that the app will crash at first launch are high.

My best guess is that this is an out of memory problem of some kind. Have you tried to reduce the resolution of these huge 8192*4096 monsters? Keep in mind that, when combined with mipmaps, each of these will use around 200mb of memory on the GPU alone (unless you are using them as 16bit variants or compress them with ETC1), let alone the VM memory.

Sooo... now this doesn't really make sense to me :/
I guess I am doing something wrong...

EDIT:
I'm starting to suspect my custom shaders...
The app doesn't seem to crash with the default shaders however my custom shaders don't give any compiling errors...

EDIT2:
Nevermind, the crash can apparently also happen with default shaders... but the crash only seems to be there for a few object3d's...

Are these messages related? Looks like it, but I've never seen those in combination with a driver error. Also, I've never seen a native driver crash without anymore detail. Can you give a little more context? What is this? A normal app? Some wallpaper? Something else?

Well, I got no clue what both of those messages mean.
However, they do appear with the fatal signal crashmessage only, yes.
Though, both of these messages you quoted do not have to appear necessarily and it will still crash with a fatal signal. (example: second log in reply #4)

I've also posted a similar log before apparently; see reply #7 on http://www.jpct.net/forum2/index.php/topic,4669.0.html
In some way it looks similar, but that is another device however. (HTC Desire 826)
I'm currently using a ZTE Axon 7 because that other phone broke.

And yes, this app is a live wallpaper.
Some info:
All objects (about 5 or 6) use the same model/mesh using "new Object3D(anotherObj, true);"
These are basically spherical objects as the app shows a small part of the solar system.
The crash happens when I launch a preview activity of the live wallpaper from the mainactivity but also when the live wallpaper is applied, it still happens.

I tried to mess around with the app earlier... And it seems that when 2 objects are added to the world, the crash happens. It doesn't matter which of the two. It doesn't matter if I set a texture for them or not. It doesn't seem to matter when they are added (before or during runtime). Once one of both is added AND is visible: crash.
I couldn't reproduce this for the other objects which use the same mesh... So I'm a bit lost here.

I'm pretty sure that it has something to do with the fact that this is a live wallpaper, but I've no idea what actually causes it. jPCT-AE doesn't care about the context in which it's running, so I really don't see what should be wrong on my part here.
It might be worth a try to set http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#useVBO to false very early in the app to see if that changes something.

Well it only seems to crash whenever I add one of the two Object3D's to the world (and if they are visible)... Like I tried to describe in my previous post...
I don't really understand what makes these Object3D's so special from the other Object3D's... :/
Settings Config.useVBO = false didn't fix the issue...

So I doubt it actually is the live wall-paper now...

Makes no sense to me. What's that thing with the SensorManager and such? Can you create a test case that's not a wallpaper but shows the crash with minimal code?

Euh, SensorManager is an Android thingy to control certain sensors in devices; such as gyroscope/accelerometer/compass etc...
I tried to make a testcase without any luck... so instead I decided to use the original code and scrap as much as possible from it while still being able to recreate the error.

So is the snippet for the activity class, should work in onCreate():
Code: [Select]
final GLSurfaceView viewer = new GLSurfaceView(this);
viewer.setEGLContextClientVersion(2);
this.setContentView(viewer);
viewer.setRenderer(new TestCaseRenderer(this,true));

And here is the link to the testcase files: https://dl.dropboxusercontent.com/u/47988037/Android/Earthify%203D/v3.8.0/beta2/testcase.zip
The ZIP file includes:
- 1 Java file (I kind of merged some classes within the class itself (in the original these classes would be there in a seperate Java file) but this shouldn't be a problem in my eyes...)
- 6 shaders (3 x fragment and 3 x vertex)
- 1 texture (apparently I can still recreate the crash with only one texture applied to the objects)
- 1 serialized model file (created using jPCT desktop version)
Note: There are probably two lines you might need to change when testing this Java file yourself, which is the package/first line and an import line.

And my crashlog using this testcase (would be pretty useless if the testcase didn't crash  ::) ):

So I also tried Google'ing around but no luck...

I can't reproduce the problem with this test case. I had to replace the cloud shader by the sun shader though, because the vertex shader for the cloud stuff was missing. But I don't think that matters. I tested it on a Nexus 4 with an Adreno 320 running Android 5.1.1 and a Nexus 5X with an Adreno 418 running Android 7. Both worked just fine.
Is this the only application that has a problem or is this a general problem? Does https://play.google.com/store/apps/details?id=com.threed.jpct.games.rpg work?
I also don't think that the thread you've linked to is related, even more so as it also crashes without using VBOs.

Hmm, well I remember having the exact same issue on my previous phone (which coincidentally also has an Andreno GPU)
It was less likely for me to be able to reproduce the problem with this testcase, 9 out of 10 times it would work normally...
While in my normal application it's the other way around, it won't work 9 out of 10 times with specific settings.
For some reason using a higher poly model than the one I sent in my last post makes crashing seem less likely.
But also using a very low poly model seems to make crashing less likely on my device.

Errr, sorry for messing up the shaders, I sent the wrong one... But shouldn't really matter anyway I guess.

But yeah, this is the only application I'm experiencing such weird issues with...
Your Naroth game works fine :) I remember it also worked just fine on my HTC Desire 826 in the past.

I could send you an APK of my full app in PM in the hope you will be able to reproduce the bug...
And perhaps send you the majority of the project in PM as well if you are able to reproduce it.
