           Summary: Non-stantard code in test 980519-2.f
           Product: gcc
           Version: 3.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: billingd@gcc.gnu.org

Steven Kargl (kargl@troutmask.apl.washington.edu) reports:

980519-2.f contains illegal Fortran; yet g77 compiles
it without a warning or an error.  A cut-down version 
of 980519-2.f is

      subroutine simul_trace(in, Xsp)

      common /Idim/ jT_f, hd_T, jT_l
      
      real Xsp
      real in(jT_f-hd_T:jT_l)
      
      in(jT_f-hd_T) = Xsp
      end

The expression jT_f-hd_T is illegal because
hd_T is a real variable.
