Summary0004617: Ardour 3 tempo assertion fails when opening project
Descriptionardour-3.0: ../libs/ardour/tempo.cc:2450: Evoral::MusicalTime ARDOUR::TempoMap::framewalk_to_beats(ARDOUR::framepos_t, ARDOUR::framecnt_t) const: Assertion `tempo' failed.

This has only happened when I created, saved and tried to reopen a project that used 3/4 time. There's one audio and one MIDI track, with the MIDI in being my controller keyboard and the MIDI out going to my Korg Wavestation. 0004614 is showing another problem with this assertion.

Core dump is too huge to attach, it's here: http://30melons.co.uk/~james/core. Don't know how useful it is.

After updating to current SVN (should probably have done that before reporting the bug) the message is now:

ardour-3.0: ../libs/ardour/tempo.cc:1912: std::vector<ARDOUR::TempoMap::BBTPoint>::const_iterator ARDOUR::TempoMap::bbt_before_or_at(ARDOUR::framepos_t): Assertion `i != _map.begin()' failed.

This appears to be the same as bug 4614, so this is now a duplicate. Sorry for wasting everyone's time.

 Following some SVN updates today, the behaviour has changed and Ardour now segfaults instead of aborting when opening this project.

Up to date core dump will be at http://30melons.co.uk/~james/core - in the process of uploading it now. (Can a developer tell me if these core dumps are actually useful? Only they're too big to attach here and it takes ages to upload them to my web server.)

I imagine this is something that is being worked on (since tempo.cc has changed in every svn update I've done) but I'm reporting it anyway.

And it seems this isn't a duplicate of the other bug after all, since the project attached to that one still causes my up-to-date Ardour to abort, rather than segfault.

I finally read up on the correct procedure for working with Ardour core dumps (never been that good with GDB) so I can do something more useful than upload them.

The debugger's initial message is:

Program terminated with signal 11, Segmentation fault.

51 return (60.0 * sr) / _beats_per_minute;

And the full backtrace:

So, the problem doesn't seem to be the original problem (a failed assertion). It now seems to be an issue with the return value of the frames_per_beat() function. Could this really be related to the fact that the project I've created uses 3/4 time? It's just that so few people ever use a meter other than 4/4 that it might not be as well tested.

Will keep on updating my SVN. Thanks developers for your continued work.

Just recreated the session that segfaulted Ardour bit by bit. Everything worked up until I recorded an audio clip of the MIDI track playing my hardware and saved. Totally bizarre. Backtrace was as above.

I'm offering an extra $25 donation, on top of the $25 I put in on Jan 6, to pay for the fixing of this bug.

i don't feel good accepting money for fixing my own coding errors. so feel free to donate, but not for this fix, please :)
