334.16 sigsev in eglCreatePbufferSurface

The attached program crashes after ~500 iterations.
I assume this is a driver bug?

After the first crash the number of iterations decrease
slightly, so it crashes earlier, eg: 480 iteration.

ok, I don’t see a button to actually add the attachement.
Here’s a link:


egltest.cpp (2.91 KB)

note: The Attachment button appears after the posting.

I have received one statement that the egltest program did run for 10 minutes.
Normally it crashes in ~10 seconds:

Segmentation fault

So it looks to be card specific.
Can someone test other cards as well?

Crash: GeForce GTX 660 Ti

On my GTX 580 it crashed after 297 first now at 310 sometimes at 305.

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff464edc2 in ?? () from /usr/lib/libnvidia-eglcore.so.334.16

Thx, blackout24.

I have another card:

  • Quadro 600

Crash: ~246 iterations.

I already send a bug report to NVIDIA. The person who said that it works
for him was the NVIDIA support. They asked me to post the issue on this board
to see if other can reproduce the problem. So probably the next release has
the problem fixed. (Given that there is no error in my EGL setup code)


crash in 124, 166,…

Thanks, sL1pKn07.

NVidia support can now reproduce the problem too, and they say its a bug
which will be fixed.
(The current 334.21 still has the problem.)
