I'm programming an extension for python to use some cuda functions, in a linux 32bit box. The module run ok without any cuda functions, but when I enable cuda functions it execute ok but end with an segmentation fault.
To check what is happening I used the python debugger and the gdb debugger. The following traceback I got at the end of the execution: (gdb) backtrace #0 0xb7ac701d in ?? () from /usr/local/share/cuda/lib/libcudart.so #1 0x00000001 in ?? () #2 0x000000d9 in ?? () #3 0xbff3e6a4 in ?? () #4 0xbff3e6e8 in ?? () #5 0xb7ab67a6 in __cudaUnregisterFatBinary () from /usr/local/share/cuda/lib/libcudart.so Backtrace stopped: frame did not save the PC Can you help me?  I got the same traceback using -deviceemu flag. If you need the code to reproduce it, I can attach it, it's free
