Assertion failed on Raspberry Pi 2

[cstranex]

Compiled current branch of libavg on the Raspberry Pi 2 successfully finally. I've run a couple of the sample apps and I'm getting assertion failed errors with some, others seem to work fine.

samples/anim1.py has "Assertion failed in GLContext.cpp: 429"

Could you run the tests and submit the complete output?
Also, does the second error always happen or just sometimes? It doesn't look like it has anything to do with the actual program being executed, so it would be good to find out under which circumstances things break.

Running the tests came up with the following:

The segfault made take a look at the Pi's memory split, and I noticed it was still set to 32MB for video memory. Increased that and now anim1.py and abort_coordinates.py appear to work. After changing the memory, I re-ran the tests and I get a segfault, but this time later:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

This happens when if I comment out everything except the rect node and the first Scroll Bar. I have also tried using the Keyboard widget which also results in a segfault and using the scroll area widget also crashes.

Could this be related to the previous error of "testCanvasEventCapture (OffscreenTest.OffscreenTestCase) ... Segmentation fault" ?

[uzadow]

Thanks for looking at this!
The tests usually do a pretty good job of finding and isolating bugs, so let's focus on those first.
I've chenged the order of the tests so the offscreen rendering stuff comes later (it makes sense to run the easier tests first anyway). Could you do a git pull and run the tests again? (no need to recompile everything, a make check should just work.)

[uzadow]

Also, #627 shows no segfaults and just a few test failures on a RPi 2, so your segfaults might be configuration issues - you might want to check for differences in the two configurations.

uname -a for my Pi is the same as #627 : Linux raspberrypi 3.18.7-v7+ #755 SMP PREEMPT Thu Feb 12 17:20:48 GMT 2015 armv7l GNU/Linux

This happened with my memory split to 128MB for GPU and 768MB for CPU.

I see that #627 is testing 1.8.1 and not the latest branch so that could potentially be the reason. I will checkout 1.8.1 and see what happens there.

[cstranex]

Hmm, well I checked out 1.8.1 and it seems to compile fine and run the tests as well as as a couple of the sample files. However I'm getting the assertion errors with my own application:

Release 1.8.2 seems to be the same as 1.8.1. Still getting assertion failures on my app.

Checked out the latest commit and I'm getting a test failure:

Please report to uzadow@libavg.de

[uzadow]

I have a running RPi cross-compile here now and an RPi 2 to test things on, so I should be able to get this fixed soon.

[uzadow]

Update: I spent the weekend reproducing and trying to fix the crash. I can reproduce it, but there's no fix yet.

[cstranex]

Ah okay, what is causing the problem? A relatively simple fix?

[sissou92]

Hello,

did you try to increase the size of your A3 memory ?

Run sudo raspi-config
Choose 8 Advanced Options
Choose A3 Memory Split
Change the value from 64 to 128 or 256

[uzadow]

Sounds very good. I won't be at my Pi before middle next week, but I'll check things then.

[cstranex]

Hmm, I'm pretty sure I tried changing the memory split but I don't think that resolved it... is the any clear way to tell if the crashes are caused by running out of memory?
