           Summary: ICE(segfault) after -std=f95 diagnostic error
                    involving PROCEDURE
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: error-recovery, ice-on-invalid-code
          Severity: normal
          Priority: P3

Follow up to bug 48279 comment 7 and 48279 comment 11.

The following program segfaults with -std=f95 after printing the diagnostic:

    procedure get1
                  1
Error: Fortran 2003: PROCEDURE statement at (1)
f951: internal compiler error: Segmentation fault


Valgrind shows tons of errors, starting with:

==22545== Invalid read of size 8
==22545==    at 0x52FD8C: resolve_symbol (resolve.c:10004)
==22545==    by 0x54BA76: traverse_ns (symbol.c:3379)
==22545==    by 0x53919B: resolve_types (resolve.c:13261)
==22545==    by 0x52E3D3: gfc_resolve (resolve.c:13357)

The testcase:

  interface get
    procedure get1
  end interface

  integer :: h
  call set1 (get (h))
contains
  subroutine set1 (a)
    integer, intent(in) :: a
  end subroutine

  integer function get1 (s)
    integer :: s
  end function
end
