Sauerbraten Segmentation fault
« on: December 09, 2015, 05:54:13 pm »
Well, this happen to me when i play a Bot Match: effic ctf on map capture_night. Maybe with another maps and mod is the same, i dont know.

I thought it was some bug on my client but then i tested on the vanilla client and was the same bug.

this is the exit on the terminal (linux):
Code: [Select]
[email protected] ~/sauerbraten $ ./sauerbraten_unix -g"consola.txt"
Using home directory: /home/alebrije/.sauerbraten/
Setting log file: consola.txt
ViolaciĆ³n de segmento

And the log file is attachment.

1. SO: Linux Mint DE 64-bits Cinnamon (201503)
2. Renderer: Gallium 0.4 on AMD ARUBA (X.Org)
   Driver: 3.0 Mesa 10.3.2
3. Sauerbraten Collect Edition
4. backtrace in the link (pastebin)
5. Description of the problem is in the begining of the threat.

But i haved got the same bug on Ubuntu and OpenSuse.

i compiled sauerbraten whit the option -g3.
And the exit using gdb: http://pastebin.com/J2PrbQ1p

This bug has, anciently, been reported in Inexor as well.
I've reopened a ticket, but none of us was able to reproduce the bug
You can find an issue right here, https://github.com/inexor-game/code/issues/251

Since current Inexor  and Alpha 0.5 (which rolls out in January) bring a stackwalker (a tool to report the exact crash cause), you could give detailed information on the problem, in case it still occurs.
