Warzone versions (2.0.4 and 2.0.5-rc1) segfault on startup right after opening a window or grabbing the full screen.
I am running it on Gentoo Linux with a 2.6.17 kernel, Pentium4 (no HT) Processor (82845 Intel Mainboard chipset), and ATI Radeon 9800Pro video card with the open-source R300 drivers. Below is more detailed info and attached is an strace dump from when I run the game (it's actually just a gzipped file, not whatever I had to pretend to make it in order to be allowed to attach it):
physfs = 1.0.1
libmad = 0.15.1b
libjpeg (http://www.ijg.org) = 6b-r4
libogg = 1.1.2
libpng = 0.6.4
libsdl = 1.2.8-r1
libvorbis = 1.1.0
openal = 0.0.8
sdl-net = 1.2.5
glut = 1.0
opengl = 7.0
IMHO - The file extension restrictions for these posts is a brain-dead idea.
