Issue with flag `-ffpe-summary` on some compiler versions #162

Open daniellivingston opened 5 years ago

daniellivingston commented 5 years ago

gfortran4.8 in TravisCI under Linux is failing when the flag -ffpe-summary is present. It passes under macOS.

Others have experienced this as well.

Consequently, I’m removing it from the Makefile until a cross-compiler version/platform solution is found.

Side-effects: some LaGriT subroutines will raise IEEE warnings such as INTEGER_UNDERFLOW.
