[Live-devel] bus error

[Matthew Romaine]

Hi Ross,

I'm occasionally running into a bus error upon connecting to the rtsp 
test code server. Often if I just start it up a second time, the 
connection is fine.

Here's some gdb output. The fPacketStart value looks rather large - 
perhaps it's not being reset somewhere? Any thoughts?

thanks,
matt
