Here's a traceback (this is ioquake3 running Quake III Arena, not openarena,
but it's basically the same), with debug symbols for as much as I could get,
and ioquake3 and SDL rebuilt with debug. I've added a bit of commentary but
not deleted anything from the traceback.
This is with s_alDevice "ALSA Software".

(Does this mean the SEGV was provoked by LWP 1508?)
Not sure what this next thread does... it might not have initialized its stack
properly yet?

This looks like an ALSA output thread:

This one looks like the interesting one: it's the PA thread:

Here's the code:
744 if (s->requested_bytes > 0 && s->write_callback)
745 s->write_callback(s, (size_t) s->requested_bytes, s->write_userdata);
So it looks as though s->write_callback is somehow broken.
I've seen a similar crash for o->stream->latency_update_callback in
stream_get_timing_info_callback.
