           Summary: Throw_2 SEGVs on Tru64 UNIX
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcj
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ro@gcc.gnu.org
              Host: alpha-dec-osf5.1b
            Target: alpha-dec-osf5.1b
             Build: alpha-dec-osf5.1b


After PR libgcj/49314, the last remaining libjava testsuite failure on Tru64
UNIX
is

FAIL: Throw_2 execution - source compiled test
FAIL: Throw_2 -findirect-dispatch execution - source compiled test
FAIL: Throw_2 -O3 execution - source compiled test
FAIL: Throw_2 -O3 -findirect-dispatch execution - source compiled test

Running it under gdb, I find

Program received signal SIGSEGV, Segmentation fault.
