Just a status update, I've been able to reproduce the problem running
darwinx86 in qemu. It's looking like this is a compiler bug with gcc-4.0
(at least Apple's) and vm_x86.c.

I was able to build a working tremded.x86 using gcc 3.3 on darwin, but
building with the included gcc 4.0 compiler had the same issue running the
.qvm as people report with my ioquake3 UB.

Unfortunately you _must_ use gcc 4.0 to use the MacOS 10.4u SDK, so this will
have to be fixed (or worked around in vm_x86.c).

The gcc-4.0 that comes with XCode 2.2 is 4.0.1, so maybe it's been fixed since
the current release is 4.0.3. I'm downloading Xcode 2.3 with my fingers crossed.

Has anyone tried building ioquake3 with gcc 4.0 on any other x86 platform?
