A few more notes: I've not used any automation in this session at all. Choosing 'Region envelope visible' on the region in question doesn't show any automation points at all. 'Reset region envelope' causes the default 0dB envelope to appear on that region, after which resizing it works as expected. |

I just experienced the same in 3.0 (rev 7504). What i did: - Import a sound file to a stereo track (track 1) - Create a _new_ track (track 2) - Cut out a region from the sound file on track 1 - Move the new region to track 2 - Resize the start of the region Ardour crashes with ardour-3.0: ../libs/evoral/src/ControlList.cpp:681: void Evoral::ControlList::truncate_start(double): Assertion `!_events.empty()' failed |
|
|
Further investigation suggests that the move-to-new-track part is not necessary for getting the assertion failure. |
|
|
Confirmed in 3.0 (not checked in 2.0, yet). |
|
|
Should be fixed in A3 SVN (rev 7510). Could you check, moshisushi? |

Seems to be a little better now! I imported a drum loop, tried to resize the start of it in different ways. Couldn't make it crash that way. Then i moved it to another track and resized, still no crash. However, i found that these steps will always crash Ardour: 1. Import a sound file to a new track / region. 2. Make a copy of that region, and make the two regions overlap a bit (with crossfades) 3. Adjust (resize) the beginning of the first region to the right. 4. Adjust (resize) the beginning of the first region to the left. |

Seems to be a different problem though.. the use count of some region source turns negative, causing Ardour to abort execution (atomizer 100.wav is my test audio file): "Bad use dec for ZG HH atomizer 100.wav" Full backtrace attached. |

|
The problem disappears if "create crossfades automatically" is unchecked |

I've had the attached change (truncate_start-error.patch) in my local copy since I originally reported this. I can't see any ill effects from just returning rather than aborting in this case. Is there a reason this is a fatal error? |

Fixed in 2.8.12. Thank you! |
