I tried hard to do so, but still no luck... :-( What I did: ___________ First test: I used catchsegv on sarge prboom, but I got no special output whatsoever, apart from the one I'm used to get *without* catchsegv. So it seems like prboom does not actually segfault: I'm puzzled... $ catchsegv prboom prboom v2.2.6 (http://prboom.sourceforge.net/) Z_Init : Allocated 8064Kb zone memory found /usr/share/games/doom/doom2.wad IWAD found: /usr/share/games/doom/doom2.wad PrBoom (built Mar 13 2005), playing: DOOM 2: Hell on Earth PrBoom is released under the GNU General Public license v2.0.

Inside gdb, prboom freezes after some seconds of playing and there seems to be no way to regain control of the X11 session. Mouse and keyboard are ignored, apart from special key combinations. If I switch to a virtual terminal (say tty1: CTRL+ALT+F1), kill gdb, and switch back to my X11 display, then all I see is a frozen gnome2 desktop still at low resolution (the one used by prboom: 640x400): mouse is ignored, while keyboard is not and can be used to type commands inside the focused xterm. The only way out I could find was killing the X server with CTRL+ALT+BACKSPACE... ____________ Other tests: I recompiled prboom with debug symbols and no stripping. I reran the above described tests. Same results! OK, what did I fail to understand? -- :-( This Universe is buggy! Where's the Creator's BTS? ;-) ......................................................................
