I found that Warzone2100 segfaults in the campaign when the first combat begans. Just after they start shooting, WZ segfaults. If I set MALLOC_CHECK_ to 1, it shows me that the reason is heap corruption. I've tried to disable the sound - it worked, so the problem must be in the sound code, I think.
I've tried on recent Gentoo on Asus V6F00VA laptop.
I will try valgrind later.
