gpus_ReturnGuiltyForHardwareRestart crash

Question

Application crashes in presentFrameBuffer (while running in foreground, no interruption occurring).

It's not crashing in the first frame, it draws for a while then it suddenly crashes.

I don't have exact steps to reproduce, but seems related to drawing something specific, still I have no openGL error reported trough the application, including one error check right before the presentFrameBuffer. If I add glFinish before the presentFrameBuffer will crash in the glFinish.

Application is crashing with EXC_BAD_ACCESS (code=1, address=0x1) and the above callstack without any other error/log/debug info.

Here is the callstack reported at the crash:

Anyone has any clue about this one ?

Answer 1

Looks like the problem was caused by having glEnableClientState(GL_TEXTURE_COORD_ARRAY) for GL_TEXTURE1 but not providing the actual data in the vertex buffer.
