[Bug fortran/43050] -fopenmp causes segementation fault with large arrays

Thanks guys. Apparently it is a stack limitation. Using ulimit -a, the default
is:
stack size (kbytes, -s) 8192

ulimit-s unlimited is not permitted. The largest value allowed is 20000, this
isnt enough to avoid the segmentation fault.

Dominque's suggestion solved the problem, at least at first glance (not fully
tested yet). Adding -Wl,-stack_size,0x20000000 as a link option prevents the
seg fault.
