[Ardour-Dev] r2956 - open session fails

Wed Jan 23 06:55:11 PST 2008

Hi,

here with r2956 creating a new session, adding 1 stereo track (alsa_pcm:capture_[12]), 
quitting and restarting and opening that session aborts with (see gdb output below). 
Doesn't happen without adding the track.

I'm a bit irritated by the "built using 2918 ..." message and a tad more than irritated 
by the last backtrace line: "Backtrace stopped: frame did not save the PC". If it said 
"frame did not save the world" ... But this:? So the backtrace is maybe not even helpful?

Anyway, thanks for "set tempo from edit range", very nice, and a great ardour 2.2,
Wolfgang
