Summary	0000595: Removing "master out" will result in crash
Description	To reproduce: 1) Create new session 2) Remove "master out" buss 3) Add a new buss Ardour crashes.
Additional Information	I'm testing beta 17.1 It appears that Ardour runs with the expectation of always having a valid master out buss (ARDOUR::Session::_master_out) Look at line 1482 of session.cc (Session::remove_route()). If &route == _master_out you're in trouble since _master_out becomes a dangling pointer after the route is deallocated. Adding the code after session.cc, line 1483: if (&route == _master_out) { _master_out = 0; } seems to fix the crash, but I'm not sure if that breaks the behavior that was intended. Are you supposed to be able to delete the master out?

paul 2004-07-09 16:27 administrator ~0001207	fixed in CVS, along with a related patch for control outs. thanks for your tracking this down. its not "expected" to remove these busses, buts its UI decision, and so the backend should handle it.
