Gfortran "ffpe-trap" compiling options

I want to use gfortran compiling options -g -fbacktrace -ffpe-trap=zero,overflow,underflow,invalid,denormal -Wall -fcheck=all to compile the test code which has invalid IEEE_XXXX_FLAG. compiler: WSL ubuntu 20.04 gfortran 9.3 The code like this program main implicit none real::a,b,c a=0.0 b=0.0 c=a/b write(*,*)c pause end program main If I don’t use these options, the output shows below (pause is important) $ gfortran test.f90 && ./a.out test.f90:8:9: 8 | …

If you are using gfortran ,you can read this

if you are using ifort/ifx, -g -traceback -fpe:0 -check all is same as gfortran’s

It is useful to check floating error
