Well, the preprocesed source is unfortunately very huge...
But I ran out of time to strip that unknown code down.
I will try to attach it...

I get the same error ("internal compiler error: in move_insn, at
haifa-sched.c:1963") when trying to compile EiffelStudio on Mac OS X PPC, also
GCC 4.2 . However it's hard to tell where it fails exactly because the error is
in some generated c-byte-code... However compilation works with Apple's GCC
4.0.1

Testcase

Compile this file with -O2 or higher to trigger the bug, no other flags
necessary. With -O1 it compiles fine.

I am seeing the same thing on powerpc405, gcc=4.2.1, openssl-0.9.8e.

I confirmed what Jann had noticed. 

Fails with -O3 & -O2.  Finishes with -O1

With -O3:

One should note that this is undefined code anyways and most likely will not
work once compiled with this version of GCC.

The next release of OpenSSL will have this problem fixed.

Well this doesn't fix the bug in GCC. An ICE shouldn't happen, even with
invalid code.
