             Bug #: 57086
           Summary: Internal compiler error: Error reporting routines
                    re-entered.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.3
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: madars+gccbug@gmail.com


The code is obviously wrong, but it shouldn't give ICE.
