seems -m64 is causing the issue.
This is an ICE in your system compiler, for which you haven't explicitly specified a version. I could not reproduce the failure using current mainline or gcc-3.4 branch compilers, so it seems like this problem (if real, ie. not due to a miscompiled system compiler) has already been fixed.
