[pulseaudio-discuss] Trying to debug segfault in pa_mainloop_dispatch().

We have adopted use of the pulseaudio library in the framework I work on
(libcinder) and we are just beginning to do production work with it. I've
hit a snag however, and I'm searching for ways to debug. Very occasionally
(less than twice a day), I'm seeing the application segfault with the
following backtrace on the audio thread:
#0 0x00007ffff61451c9 in pa_mainloop_dispatch () from
#1 0x00007ffff61454bc in pa_mainloop_iterate () from
#2 0x00007ffff6145560 in pa_mainloop_run () from
#3 0x00007ffff61537a9 in ?? () from /usr/lib/x86_64-linux-gnu/libpulse.so.0
#4 0x00007ffff0ef0078 in ?? () from /usr/lib/x86_64-linux-gnu/pulseaudio/
#5 0x00007ffff58416ba in start_thread () from
#6 0x00007ffff4cd63dd in clone () from /lib/x86_64-linux-gnu/libc.so.6
I haven't been able to track down if we're doing something wrong from the
client side yet, though I was wondering if there is a way to turn on some
sort of verbosity to track this sort of thing, or it sticks out to some
folks as far as some things I can check?
For reference, our usage of the pulseaudio backend is primarily here:
