Does it work if you compile without the USE_GML* flags? (Probably not, but I have not tested with them since I do not own a multi-core CPU)

If not, what kind of processor does your machine have?

Lupus: could you compile and run the attached source file (cpuinfo.cpp) for me? Just do

g++ -Wall -Wextra -O2 -g cpuinfo.cpp -o cpuinfo
./cpuinfo

from a terminal and see what is printed. Thanks.

It should have crashed? :)
I tried to compile this commit once more to be confident. It crashes with or without GML stuff.

 Great! Guess my asm isn't what it used to be; I got the replacement code (which is simpler to boot) from the bochs emulator project. I'll commit it to master.

Edit: done. Could you compile and test one last time to be sure everything's OK now?

 Sure. Downloading 201f57367156485dbe922a4437e034af6af58d9d...
EDIT: At least it runs. But it hangs on mod selection menu :-p Rebuilding in Debug...
