I have been trying to create some OpenGL examples for PyCUDA
and found program that segfaults.
I cannot debug it fully as the last 8 functions are from
The last known function in the trace is cuda::context::detach.
Error is present on GTX460 (Fermi) and ION (9400M),
on PyCUDA with my patch and without it.
Debian 64-bit, kernel 2.6.32, drivers 256.53, CUDA 3.1.
PyCUDA from git.
Can someone look at program and stack trace and tell whether
there is some obvious mistake I am missing?
If not, I think I will report upstream bug to NVIDIA.
Doesn't appear to crash with 260.24. (3.2RC available from Nvidia if you
sign up for their developer program) Haven't tried 3.2rc2.
I lied. It does crash when you close the window.
(2.6.35, amd64, 260.24, 3.2rc)
So is this error in my code or CUDA?
BTW - I do not want to install 3.2rc for now,
as I am still trying to convince Debian Release team
to accept PyOpenCL 0.92 into Squeeze and need to be
able to build it with stable versions of libraries.
