PR fortran/33269
fortran/ * io.c (check_format_string): Move NULL and constant checks into this function. (check_io_constraints): Call gfc_simplify_expr() before calling check_format_string(). Remove NULL and constant checks. testsuite/ * gfortran.dg/fmt_error_2.f90: New. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@128732 138bc75d-0d04-0410-961f-82ee72b054a4
