[mythtv-users] 0.15 mythbackend crashes (backtrace included)

[Alexander Varakin]

Hi,

I recently upgraded Myth 0.14  to 0.15 and I started getting crashes of 
backend.
It crashes not more than once a day, normally few minutes after starting 
recording.
Both scheduled and live recordings cause crashes.

My system is Debian unstable.  Capture card id bttv based.
I tried Debian binary packages, built Myth myself from CVS, nothing helps.
Compiler is gcc (GCC) 3.3.3 (Debian 20040422).

I built Myth from CVS, using  debug config but with -O3 turned on.
I got it crashed, backtrace is:
