My (x86_64) Fedora 6 box recently updated to gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13) Unfortunately, this version of gcc consistently gives "internal compiler error: Segmentation fault." when used with the C codegen. I don't know if the ICEs are also present on i386. I've filed a Fedora Bugzilla report: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=247407
