Fedora Core 3 has gcc that miscompiles lapack with high optimization.
You can grab lapack from the rawhide. If you compile octave
w/o external lapack (and using the included one) you
have to set FFLAGS to -O1 or to -ffloat-store.
See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=138791
for details.
