re PR fortran/88269 (ICE in gfc_format_decoder, at fortran/error.c:947)
2018-12-10 Steven G. Kargl <kargl@gcc.gnu.org> PR fortran/88269 * io.c (io_constraint): Update macro. If locus line buffer is NULL, use gfc_current_locus in error messages. (check_io_constraints): Catch missing IO UNIT in write and read statements. io_constraint macro is incompatible here. 2018-12-10 Steven G. Kargl <kargl@gcc.gnu.org> PR fortran/88269 * gfortran.dg/pr88269.f90: New test. From-SVN: r266959
