Look at my backtrace - libGL.so, nvidia, mesa

Hi,

Please have a look at the backtrace and advise on whether to post a bug or not.

The problem is that the libGL.so supplied with Linux nvidia driver 310.19-2 thows a segmentation fault with my program but if I replace it with the libGL.so that comes from mesa, it works.  Unfortunately the test program is quite hard to install and comes from dolfin-bzr in the AUR, it is a demo at demo/pde/poisson/cpp.

After the segmentation fault, starting gdb with the dumped core file gives this backtrace:
