> * config/linux/proc.c (gomp_cpuset_size, gomp_cpusetp): New variables.
> (gomp_cpuset_popcount): Use CPU_COUNT_S if available, or CPU_COUNT if
> gomp_cpuset_size is sizeof (cpu_set_t). Use gomp_cpuset_size instead
> of sizeof (cpu_set_t) to determine number of iterations.
> (gomp_init_num_threads): Initialize gomp_cpuset_size and gomp_cpusetp
> here, use gomp_cpusetp instead of &cpuset and pass gomp_cpuset_size
> instead of sizeof (cpu_set_t) to pthread_getaffinity_np.
> (get_num_procs): Don't call pthread_getaffinity_np if gomp_cpusetp
> is NULL. Use gomp_cpusetp instead of &cpuset and pass gomp_cpuset_size
> instead of sizeof (cpu_set_t) to pthread_getaffinity_np.
> * config/linux/proc.h (gomp_cpuset_popcount): Add attribute_hidden.
> (gomp_cpuset_size, gomp_cpusetp): Declare.
> * config/linux/affinity.c (CPU_ISSET_S, CPU_ZERO_S, CPU_SET_S): Define
> if CPU_ALLOC_SIZE isn't defined.
> (gomp_init_affinity): Don't call pthread_getaffinity_np here, instead
> use gomp_cpusetp computed by gomp_init_num_threads. Use CPU_*_S
> variants of macros with gomp_cpuset_size as set size, for cpusetnew
> use alloca for it if CPU_ALLOC_SIZE is defined, otherwise local
> fixed size variable.
> (gomp_init_thread_affinity): Use CPU_*_S variants of macros with
> gomp_cpuset_size as set size, for cpuset use alloca for it if
> CPU_ALLOC_SIZE is defined, otherwise local fixed size variable.

Did this fix it?
(also I'm kind of jealous of anyone with a computer with that many cores...)
