           Summary: GCC 3.2.3 Internal Error Using -m128bit-long-double on
                    x86
           Product: gcc
           Version: 3.2.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org

I compiled gprof using GCC 3.2.3 with -m128bit-long-double optimization and GCC 
crashed. It also fails on 3.0.4, 3.2.1, and 3.3.1 (6/26/2003 Debian prerelease).

Here is some info/repro:

# gcc -c -m128bit-long-double cg_print.i
cg_print.c: In function `cg_print_function_ordering':
cg_print.c:869: internal error: Segmentation fault
