Crash on x86_64?

[brendanburns at comcast.net]

Hey folks,
Just got around to trying this with on my x86_64 Debian box, I'm using the demo pak0.pk3 since i don't own the game.  

I start quake with:

./linuxquake3 +set sv_pure 0 +set vm_cgame 0 +set vm_game 0 +set vm_ui 0

Everything launches fine, but when I try to start a single player game it dies.  Running it in gdb, 
I see that it dies on line 840 of qcommon/cvar.c with a segfault.  Based on the comments, this function seems to be vm specific.  Should it not be called with vm_foo set to zero?

I'll play around some more, but if someone on x86_64 has this working, let me know!

Thanks in advance!
