pb2 segfaults on linux after pressing a key when resolution was changed

[psychon]

First of all: this game is great.

Every time i change anything in the Video Settings tab, pb2 segfaults after pressing any key.
I use gentoo linux and here is a backtrace produced via gdb:
Program received signal SIGSEGV, Segmentation fault.

On start it says: Paintball 2 -- Version 3.21+r0.16

Hope this can be fixed...

Thanks for the report.  I may not be able to reproduce it.  Is there any chance you could compile the source and run the debug version to find out exactly where it crashed?

Also, aside from crashing after changing resolutions, does everything else run OK?  Lots of people have had problems with the sound and mouse input.

[XtremeBain]

I think I had the same problem, but I had fluxbox launch pb2 and never thought to run it from console to grab the seg fault info.

[psychon]

if you give me the link, i would like to test it (i newer saw that link) and no, my sounds doesnt workd either:

recursive shutdown

sound newer worked and i dont know why. and it is not just changing resolution, it's after changing ANYthing on the cideo tab.
mouse problem are there too, they come and disappear. didn't anoy me so far .
and no, i dont know how to enable XFree86-VidModeExtension, i just managed to enable the dga thing

[psychon]

so the next one...(now finally i registered):
i found the source zip-file and this is the result:
psycho@LiNuX ~/Eigene Downloads/paintball2 $ make

anything i have to know? the readme.txt didnt help so far...

EDIT:
 mkdir debugi386/a3d
make build_debug

that works for a while but then:

i cut off the warnings and translated from german to english...

EDIT2:
so i disabled alsa (sound doesnt work with this version, too) and here is the output:

i changed the resolution, started a game (only once) and tried to walk (press w)

[jitspoe]

Hm, it looks like all that stuff is within libX, not within paintball2.

Well, I think I have a general idea of what's causing the problem.  The linux code is a real mess.  The input is tied in with the video library.  When you change video settings, it completely reloads that library.  Something must not be loading properly.  What distro are you using?

[psychon]

im using gentoo linux, pretty much the stable version.

[XtremeBain]

I was using gentoo as well, on a 2.6 kernel.
