Hi all
I started fgfs from fgrun on my Linux machine and I was sitting at KOAK.
No AI-traffic enabled nor traffic-manager. The airplane was my usual
Aerostar700. Terrasync is running and so is fgcom, but nothing special
is going on. I was just sitting on some taxiway, engines running, for
about 10 minutes. I was checking my Email. My fgfs was compiled today
from the latest git sources.
And suddenly, sound stopped and I get a segfault with the following
stack backtrace:
[TRACE]
Program terminated with signal 11, Segmentation fault.

[/TRACE]
I did have a crash earlier today, but did not pay attention. Not enough
at least.
I hope this report helps...
