[Bug c/24443] New: unrecognized instruction with -fPIC and -O with 4.1-20051015

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hello there,

I just tried to compile some parts of Suse Linux with GNU C compiler
4.1 snapshot 20051015 on an x86_64 machine, and the compiler said

-----------------------------------------------------------

linux:/usr/src/packages/BUILD/clisp-2.33.2/x86_64-suse-linux #
/home/dcb/gnu/41-20051015/results/bin/gcc -fPIC     -O  -c /tmp/q.i

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

-----------------------------------------------------------

Note how I had to use the compiler flags -fPIC and -O to get a crash.

The bugzilla won't let me either attach the source code or put it in
this field, so I'll have to say that source code is available on
request.
