--- Comment #5 from Bill Long <longb at cray dot com> ---
I tried on my Mac laptop (gcc version 6.3.0) and it also works there. Evidently
not a representative test.  The differences I see between that environment and
the original customer's is that they are running 7.2.0, using srun (SLURM) for
program launch, and running on Broadwell processors. 

The original error
Internal Error: stash_internal_unit(): Stack Size Exceeded
suggests some issue with running out of memory.
