Using GCC 4.1.2 and compiling with -static -O2, the SPEC CPU2000 benchmark
vortex segfaults on my system (Fedora Core 4, Intel Pentium 4).

This issue was reported before (see
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23449), and seem to be resolved in
GCC 4.1.1. Using -fno-strict-aliasing solves this, but I wonder why
-fno-strict-aliasing was not required with GCC 4.1.1, but is crucial (again) in
GCC 4.1.2.

Any further details will be provided as needed.
