This is the first time the stage1 compiler is used which means it doesn't work
at all.  Please use gdb to debug it and see why it segfaults.

Not as I understand "the first time".  The end of the log looks like this:

In fact:

57

So it seems not to have failed more than a few times before failing.

I'll try to install gdb, and poke around a little, but don't expect too much.

The back story on this is that I've been adding PPMd compression capability to
the Info-ZIP UnZip program, and I was getting bad behavior on my AIX/PowerPC
and HP-UX/PA-RISC systems, while the same (public domain, probably widely
used) code was working as expected on some other systems (HP-UX/IA64 (GCC),
Solaris/SPARC (some old GCC and Sun C), VMS/Alpha (HP C), VMS/IA64 (HP C),
VMS/VAX (Compaq C)).

After too much fooling around, I discovered that compiling one particular
module with -O1 (HP-UX) or -O2 (AIX) instead of -O3 (our GCC default) would
correct the bad behavior.  A strategic fprintf( stderr, ... bad_variable) in
the misbehaving function also corrects the bad behavior.

I was trying to bring the compilers up to date, to see if I'd get lucky, and
find that there was a compiler optimization problem which had been fixed
already.  But I can't get a recent GCC build to go through on either the AIX
or HP-UX systems.  Chasing GCC build problems is approximately twice removed
from my actual problem, and I had hoped that someone who knows more about GCC
than I would be interested enough to see if this build problem can be
reproduced, at least, or if there's something especially lame about my
environment(s).  Sadly, creating a small test program which exhibits the
optimization problem does not look easy, either.  (But I could supply an
UnZip source kit (12MB), an example PPMd-using archive (7MB), and
instructions, if anyone with the appropriate hardware were interested.)

A somewhat condensed test case (1.6MB) should now be available here:

      http://antinode.info/ftp/info-zip/unzip610c08_sx.tgz

The READ_ME file therein should explain how to reproduce the original problem.
If the defect lies in the code rather than in the compiler, then I'd be happy
to get a clear explanation of it.  I suspect that this belongs in a thread of
its own, which I could create, if that would be helpful.

I've also hit this bug. I'm attempting to use gcc 4.4.2 to compile gcc 4.7.0
and 4.7.2. Neither works.
