             Bug #: 54048
           Summary: Uninitialized input_location in front-end
                    initialization
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mikael@gcc.gnu.org


Valgrind gives errors of the following kind with gfortran 4.6.3 and 4.7.1.
Can't check 4.8.0 as valgrind chokes on it (illegal instruction).

No. As far as I remember, it used to happen on any testcase, for example:

!!!
end
!!!

It seems to work now.  Valgrind reports errors, but they seem to be deep down
the middle-end, and unrelated to this.  Closing.
