| Summary | 0007248: Crash when copying a MIDI region with debug build | ||||
| Description | I have an ardour session with many MIDI regions, one of them when I try to copy it makes ardour crash, cf. output: ardour-5.5.290: ../libs/ardour/midi_region.cc:119: ARDOUR::MidiRegion::MidiRegion(boost::shared_ptr<const ARDOUR::MidiRegion>, ARDOUR::MusicFrame): Assertion `_name.val().find("/") == string::npos' failed. Aborted Compared to http://tracker.ardour.org/view.php?id=6002 I don't have "MIDI region copies are independent" checked. I `git pull`ed and rebuilt, the problem still happens (only with one particular MIDI region, the others I've tried seem fine). All the MIDI regions were created the same way, from the Ardour UI. The incriminated region, when trying "Duplicate" also crashes ardour with the same message. | ||||

Right after submitting I found out what was special: The name of the region contained a `/`. I removed the `/` and now it works. The UI should prevent the user from creating wrong names; and/or the system should sanitize the names of the regions internally. |

What was the name of the track where this happened? We do attempt to sanitize region and track and session names, btw ... |
|
|
I don't remember the actual name (sorry should have made a snapshot of the session…), I later found a couple more regions with the same problem. The names looked like "NameOfThePart /2 Bass" or "NameOfThePart/2 RGuitar" (the "/2" meant to mean "half-tempo" to me :) ). > We do attempt to sanitize region and track and session names, btw ... Sorry didn't mean to sound rude (sometimes I talk like an IETF RFC…). |

I can reproduce this with a debug build of Ardour version 5.8.54. You can still rename a MIDI region to contain a / character and then trying to copy that region results in a crash. The 5.8 release doesn't crash as it doesn't contain the assertions that check for a slash in the MIDI region name and it doesn't seem to cause any issues. The MIDI source files seem to be renamed to remove the slash, perhaps the assertions are no longer necessary. |
