Summary0001621: rc1 still crashing while reconnecting to jack
Descriptionif i try to debug with the 'ulimit -c unlimited' method, after the crash ardour does not write the core file (don't know why, think i am doing right).
but if i start ardour from /gtk2_ardour/ardbd, let him crash and than 'thread apply all bt' i get a backtrace.
to reproduce the bug:
-start new session (all default -sync internal/timemaster)
-hit play (with or without having audio in it)
-stop qjackctl/jackd
-ardour hits the message about disconnecting (sometimes information window, sometimes ardour-log window sometimes both. i don't find the logic of it)
-start jackd again
-reconnect ardour
-ardour crashes
-sometimes i have to do this twice in order to crash ardour.

last week i could not get any backtrace out of it, but just realized that i can again.

might be related to 1565 and 1616

cheers,
doc

hi, it seems that with ardour2 i cannot reproduce this anymore.
i just tried several times with internal-sync as well as with jack-sync, but ardour always reconnected to jack smoothly.

cheers,
doc
