<div class="markdown_content"><p>I've also seen once or twice another bug in pulseaudio: when starting ohrrpgce-game it immediately died with the message:<br/>
Assertion 't = find_next_time_event(m)' failed at pulse/mainloop.c:719, function calc_next_timeout(). Aborting.</p>
<p>Searching the web I see a number of reports of this, eg <a href="https://sourceforge.net/p/openmsx/bugs/555/">https://sourceforge.net/p/openmsx/bugs/555/</a>, but no mention of a fix. What they all have in common is using SDL 1.2 with pulseaudio.</p>

<p><strong> <a class="alink" href="https://sourceforge.net/p/ohrrpgce/bugs/2020/">[bugs:#2020]</a> Freeze in SDL_CloseAudio when using PulseAudio?</strong></p>

<p>About 3 times in the last couple of weeks I have seen Custom freeze when quitting, while using gfx_sdl/music_sdl on GNU/Linux (Slackware64-current), with FB 0.23 (32 bit), SDL 1.2.15, SDL_mixer 1.2.12. I think in all cases I had been resizing the window (since I've been testing that a lot lately). I can't easily reproduce it, it happens rarely. I haven't seen Game freeze in the same way. At least twice I attached gdb, and saw that the freeze was in a pthread_join in SDL_CloseAudio:</p>

<p>Notice /usr/lib/libpulse.so in the backtrace. I think what has changed is that Slackware recently switched to PulseAudio, and I see that I installed those upgrades on Jan 23. I don't remember having this problem before the last few weeks.</p>
