gcc/g++/gfortran compiler flags

Here are some useful flags to use when developing a code, or trying to find why code crashes: 

-Wall -Wextra -Wconversion -pedantic -ffpe-trap=zero,overflow,underflow,invalid 
-ffree-line-length-none -finit-local-zero -fbounds-check -fcheck-array-temporaries

Use man gcc to find details about each.

I often remove "underflow" from the list, since it just makes small floating point numbers to zero, but it is useful to know.

C++

Fortran

Python
