Crash in ukiCreateContext


I am running an

  • OpenGL app (using LWJGL)
  • under 32bit Linux
  • with an embedded ATI MXM module E4690 with 11.12 drivers

After running for hours and sometimes days the application segmentation faults in the driver method ukiCreateContext. The stack below that call is different at times, but it mostly happens when I blit an FBO after rendering to a texture, multisampled. The fact that I cannot debug, etc. into the driver and the fact that I cannot find anything on the net about this makes it hard to fix.

Java SEGV message:


# A fatal error has been detected by the Java Runtime Environment:

The top of the stack:

[error occurred during error reporting (printing native stack), id 0xb]

j  org.lwjgl.opengl.EXTFramebufferBlit.nglBlitFramebufferEXT(IIIIIIIIIIJ)V+0

What does that ukiCreateContext method do and does anyone have an idea what I may be doing wrong to cause this? Is it a known driver-bug? How shall we proceed?

Thanks for your help,
