[pulseaudio-discuss] 0.9.8 seg fault

[Jim Duda]

Lennart,

Although I haven't been able to get you a trace back, I can inform that
the crash appears to be related with using a combined_sink.  I was using
a combined_sink to drive 2 sound cards.  Once I removed that feature,
pulseaudio appears to run without segfault.

I didn't have this issue with stock fc7 0.9.6 pulseaudio.
