[http://sourceforge.net/p/ufoai/bugs/2132 Item 2132] imported from sourceforge.net tracker on 2013-01-28 19:22:20

short: UfoAi silent crash, sound toggle.

walktrough:
- UfoAi start. (default settings, english)
- start new game: single player, campaign.*
- (geoscape), options, sound.
- (sound) disable sound. (enable sound [OFF])
- (sound) [Activate Sound], or (enable sound [ON])
- (sound) disable sound. (enable sound [OFF])
+ UfoAi gone.

*) without, sound can be toggled multiple times without any side effects.
*) Skirmish instead of campaign mode: ufo-ai gone at [Activate Sound] step.

ufoconsole.log = zero bytes.

System details:

(mmm, I think I need to be able to test-run changes somehow before I can fix something)

not reproducible for rich and me

i just wanted to suggest running ufoai in gdb (see details in wiki) and providing a backtrace if the crash is reproducible

gdb console log
====== mvgulik (2009-07-03 15:09:14) ======

Added "gdb console log.txt"

gdb problem:
Can't fully duplicate the problem when running UfoAi with gdb.
UfoAi locks up when disabling the sound the first time.

additional info:
- using version 24882 instead of 24799.
- confirmed initial behavior is unchanged when running ufoai without gdb.

Reproducible since r24392. Sound may be disabled when you start game, but must be enabled when you start campaign (or load savegame).

not reproducible here - still the case in current trunk?
