[ardour-dev] One session - consistent segfault

[Mark Knecht]

Hi all,
   I have one session which consistently segfaults. I ran into this
doing some testing of a new kernel. This session, when played using
the loop play feature, always segfaults when the play head jumps back
to time 0. It also segfaults if I hit the loop play button twice,
probably because it jumps back to 0 then also.

   I'm rebuilding Ardour now with debug turned on to get more info.
All I see in dmesg right now is this:

ardour[8063]: segfault at 000000040180780c rip 000000000076545b rsp
0000000041800cc0 error 4
ardour[8104]: segfault at 00000004017ff06c rip 000000000076545b rsp

   Looking at the bad session I see one thing I don't understand. In
this session I have no loop ranges defined. The end marker is at the
end of audio, at about 4:30, but when I hit the loop play button it
highlights from 0 to 5:00, not to the end marker.

   What sets the loop playback range if it's not the end marker???? I
see that on a new session it acts the same way. Why doesn't the loop
play follow the end marker if there's not loop range set?

Thanks,
Mark
