Threa sanitizer shows, when playing gangsta_rap_se.swf:

It seems two threads are accessing sound_handler::_inputStreams at the same time. sound_handler_sdl, from its own thread, is holding a mutex lock in SDL_sound_handler::fetchSamples(), but the main thread does not hold a lock when calling sound_handler::streamingSound().
