Bug#605504: chocolate-doom: Game freezes up during play

[Simon Howard]

Package: chocolate-doom
Version: 1.4.0-1
Severity: grave
Tags: patch
Justification: renders package unusable


Chocolate Doom locks up during play.  This is due to a bug in
SDL_mixer 1.2.8 that was fixed in v1.2.9.  When using the
Mix_SetPanning function to set the left/right separation of a playing
sound effect, a race condition can occur that causes a structure to be
accessed by the main thread after it has been freed by the sound
callback thread.

A fix for the SDL_mixer bug can be found in the LibSDL HG repository,
changeset 884a700fb3ff.  This fix was included in the v1.2.9 release.
Alternatively, a workaround for the bug can be found in the Chocolate
Doom SVN repository, see revision 2165.
