SMS.f19_f19.I1850CLM45CN test fails with seg-fault on Cascade with NAG compiler

[singhbalwinder]

SMS.f19_f19.I1850CLM45CN test case is failing with the following error on Cascade with the NAG compiler:

[g1:mpi_rank_26][error_sighandler] Caught error: Segmentation fault (signal 11)
[g3:mpi_rank_52][error_sighandler] Caught error: Segmentation fault (signal 11)
srun: error: g3: task 52: Segmentation fault (core dumped)
srun: Terminating job step 1354215.0

The model crashes after 48 time steps (~1 day of run). The model crashes only when run with 64 tasks. With 1 and 8 tasks, the model runs fine to completion.

Can you reproduce this on blues?

This can be investigated on blues with with its NAG compiler.

I am looking into it now.

I haven't merged #597 yet. I thought I'd wait things are sorted out.

@singhbalwinder you don't have to. Its assigned to @bishtgautam.

ok. I just started doing it and I am running into similar problems as I was
for the atm codes. NAG doesn't like the following:

#if def SOMETHING
module a_module
....
....
end module a_module
#endif

We have to change this to:

module a_module
#if def SOMETHING
....
....
#endif
end module a_module

Basically, NAG doesn't like to compile an empty file (which will be the
case if #if def is not true). I will let Gautam handle this issue.

The #ifdef have been correctly defined for various modules.
