Catch floating point exceptions in debug build #6

Closed nichannah closed 6 years ago

nichannah commented 9 years ago

In issue NOAA-GFDL/MOM6#194 we discussed making floating point exceptions standard. Given that there may be a performance hit it would be better to do this only in debug builds.

This issue is to add:

-fpe0 (intel) -ffpe-trap=invalid,zero,overflow (gnu) - (pgi)

to the debug build in the machine *.mk files.
