Dear GROMACS users:
On "Gromacs 4.6 segmentation fault with mdrun",
I'd also met the same segmentation fault problem with gromacs-4.6.
on my linux box with GTX-580.
For my case, change the compilor solved this problem.

These were same in the version when I first met the problem.
After that, I'd tried Intel compilor instead of gcc-4.4.x,
then the GPU jobs runs without the segmentation fault.
I also tried gcc-4.6.x and it also runs without
any faults (I'm using CentOS and its gcc version is currentry
gcc-4.4.x. Then, I had to compile gcc-4.6.x from the source.
gcc-4.7.x can't use with CUDA-4.2 since it only suppoorts
up to gcc-4.6.x.).
I suggest to try either intel compilor or gcc-4.6.x instead of
