re PR fortran/40839 (gfortran segmentation fault when a unit number is missing)
PR fortran/40839
* io.c (gfc_resolve_dt): Add LOC argument. Fail if
dt->io_unit is NULL. Return FAILURE after issuing error about
negative UNIT number.
(match_io_element): Don't segfault if current_dt->io_unit is NULL.
* gfortran.h (gfc_resolve_dt): Adjust prototype.
* resolve.c (resolve_code): Adjust caller.
* gfortran.dg/pr40839.f90: New test.
