When variable-length strings are passed into functions compiled by gfortran, the lengths of the strings have to be passed at the end of the argument list as size_t. When using gcc <= 7 or clang (where the __GNUC__ macro might return unpredictable values), we were putting int on the C side, which got interpreted as size_t on the fortran side.

When variable-length strings are passed into functions compiled by gfortran, the lengths of the strings have to be passed at the end of the argument list as
size_t(since gcc 7). With clang, where the__GNUC__macro could expand to funny values, we were passinginton the C side, making fortran interpret the string lengths wrongly.fixes #19329
