            Bug ID: 95708
           Summary: [9/10/11 Regression] ICE in resolve_fl_procedure, at
                    fortran/resolve.c:13002
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

Special case "team_number" gives an ICE down to r8, r7 rejects it :


$ cat z0.f90
program p
   procedure(num_images) :: g
end


$ cat z1.f90
program p
   procedure(team_number) :: g
end


$ gfortran-11-20200614 -c z0.f90
z0.f90:2:29:

    2 |    procedure(num_images) :: g
      |                             1
Error: Intrinsic procedure 'num_images' not allowed in PROCEDURE statement =

(1)
