Subjectmodpost segfaults with 32bit compile on 64 bit version of Fedora 13

I have reported this to the Fedora bugzilla. Not getting much traction on
the problem. Maybe someone here has an idea.

I have a x86_64 version of Fedora 13. I try and build a kernel under i386
and modpost segfaults every time. (Works fine on Fedora 12 and gcc 4.4.3.)

It does not matter if I use "make ARCH=x86", i386 and make, or any other
32 bit compile I have tried.

Here is the gcc info:

gcc -v
Using built-in specs.
Target: x86_64-redhat-linux

Thread model: posix
gcc version 4.4.4 20100503 (Red Hat 4.4.4-2) (GCC)

This works under Fedora 12, but not under 13 with the exact same code and
commands. I have tested with 2.6.35-rc1, as well as other versions.

Any idea what they mangled in gcc 4.4.4 to cause this? So far the Fedora
people have claimed "it is a kernel problem".

Thanks.
