            Bug ID: 61908
           Summary: load of invalid value for 'expr_t' in interface.c
                    compare_actual_formal
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zeccav at gmail dot com

Compiling the testsuite file unlimited_polymorphic_16 with sanitized gfortran
I get the following
"../../gcc-4.9.1/gcc/fortran/interface.c:2667:43: runtime error: 
load of value 1818451807, which is not a valid value for type 'expr_t'"
The offending line in interface.c:2667 is
"&& f->sym->ts.u.cl->length->expr_type == EXPR_CONSTANT"
in compare_actual_format.

I still have the same runtime error message in 4.9.2

Trying compilation of

!from unlimited_polymorphic_16.f90
!../../gcc-4.9.2/gcc/fortran/interface.c:2667:43: runtime error: load of value
1818451807, which is not a valid value for type 'expr_t'
contains
  subroutine FWRite(S)
    class(*) :: S
  end subroutine

  subroutine IO_OutputMargeStats()
    character tag
    call FWrite(tag)
  end subroutine

end

I get

./../gcc-4.9.2/gcc/fortran/interface.c:2667:43: runtime error: load of value
