Well, after following the debugging procedure outlined above I've got nothing. Basically, the program refuses to crash unless it's being displayed by the xserver (xserver-svga 3.3.3.1-10). It can run just fine for ages while the X server is not on screen, but as soon as I switch back to the xserver, the whole systems locks (if I happen to catch the penetrate program in it's end of level display).
