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.

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".
