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. (cherry picked from commit 3a9316e)
