fortran/interface.c:2015"

    With submodules, name mangling of interfaces may result in long internal
    symbols overflowing an internal buffer.  We now check that we do not
    exceed the enlarged buffer size.

            * interface.c (check_sym_interfaces): Enlarge temporary buffer,
            and add check on length on mangled name to prevent overflow.
