gcc 2.95.2: Internal compiler error in `make_edges', at flow.c: 967

[Peter Barada <pbarada at wavemark dot com>]

Please keep me posted on any patches for this bug, Thanx.
I have many cases that cause this. I just grabbed what looked like the
shortest case here.

Compiler configured with: 

#!/bin/sh
# This file was generated automatically by configure.  Do not edit.
# This directory was configured as follows:
../../gcc-2.95.2/configure --with-gcc-version-trigger=/bigdisk/pbarada/src/new-ppc/gcc-2.95.2/gcc/version.c --host=i686-pc-linux-gnu --target=ppc-rtems-eabi --prefix=/usr/local/wave/ppc4 --exec-prefix=/usr/local/wave/ppc4 --program-prefix=ppc_ --norecursion 
# 

Command line and output is:
