[Bug c/16860] New: internal error: illegal instruction

["singularitylightspeed at yahoo dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I have encountered an internal compiler error (Illegal instruction) under Linux.

Below is the output of gcc -v:
-----------------------------------------------------------------------

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

The command-line to compile the test file is:
-----------------------------------------------------------------------
/usr/bin/gcc -pipe -g -O2 -I../include -I/usr/local/include/nessus -
DNESSUS_ON_SSL -I/usr/kerberos/include -DHAVE_SSL -I/usr/include/openssl -
DNESSUS_EXTENSIONS -I. -I/tmp/nessus-installer.10304/libnasl/include -
DHAVE_CONFIG_H -c md5.c  -fPIC -DPIC -o .libs/md5.lo

OR:
/usr/bin/gcc -c -O2 md5.i

-----------------------------------------------------------------
I've got the following output from the compiler:
md5.c: In function MD5Update':
md5.c:102: internal compiler error: Illegal instruction
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.openpkg.org/> for instructions.
----------------------------------------------------------------
My machine is an AMD K6-2 running RedHat Linux 9; kernel 2.6.5.

I have installed a binary precompiled version of gcc from openpkg(openpkg.org).
The file md5.c is from nessus version 2.1.1 (nessus.org).
If I use the gcc version 3.3.3 under Linux it works ok.
Note that if I use gcc 3.4.1 compiled for mingw32 it compiles the above file ok.
I have downloaded it from the mingw site, the output of gcc -v (mingw32 
version) is:
