I'm seeing this too. Happens if I close a session with audio in it. Doesn't happen on an empty session. It means you can't switch sessions with having to restart ardour.

The problem seems to be iterating through the audio_regions in Session::~Session... |
|
|
When I comment out the code that deletes the audio_regions, I no longer get a seg fault. Obviously this causes a memory leak instead :( But this is definitely the source of the problem. Why deleting the audio_regions causes a seg fault I haven't figured out yet. |
|
|
Seems that when playlists are deleted, their associated regions are deleted too, but not removed from audio_regions in Session. When ~Session runs it tries to delete the AudioRegion objects, but any which were part of a Playlist have already been deleted, hence seg fault. I haven't been able to figure out what part of the Playlist code deletes the regions, it all seems a bit magical. |

When an AudioRegion is destroyed, it emits a GoingAway signal. This is attached to Session::remove_region(). In ~Session, the AudioRegion objects in audio_regions are deleted using an AudioRegionList::iterator. Each delete results in a call to Session::remove_region(), which attempts to modify audio_regions while it is being iterated over! This is easily fixed by making a copy of audio_regions to iterate over for the delete. Patch in mantis. Please commit! |

believed to be fixed in CVS. let me know. |

Looks good |
