Description
While testing something for issue #311 I tried running the stochastic physics in a build that was built with the debug options. I set SKEB: 1 and SPPT: 1 in the AGMC.rc which seems to be the flags to turn this on. When running with debugging the code crashed like so with an out of bounds error:
GEOSgcm.x 000000000198A11C interp_h_ 369 interp_h.F
GEOSgcm.x 0000000001861428 gauss2grid_ 80 gauss2grd.f90
GEOSgcm.x 0000000001858DF9 stoch_module_mp_g 311 stoch_module.F90
GEOSgcm.x 000000000184E44C stoch_module_mp_s 140 stoch_module.F90
GEOSgcm.x 00000000017B6DC2 geos_physicsgridc 2650 GEOS_PhysicsGridComp.F90
So something is not right. When running with the release build it does not crash.

Research direction
Reproduce the debug build with SKEB: 1 and SPPT: 1 in AGMC.rc, then inspect the reported locations: interp_h.F line 369, gauss2grd.f90 line 80, and stoch_module.F90 lines 140 and 311. Trace the out-of-bounds access and verify that stochastic physics completes without the debug crash.
