I can confirm this problem; also using other gcc versions :-(
x86: gcc version 3.3.3 20040412 (Gentoo Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6)
amd64: gcc (GCC) 3.3.3 20040412 (Gentoo Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6)

Would youu mind taking a look at it then.  I'm swamped =)

Patched to make code compatible with more strict GCC checking.
Committed to CVS.
