| Summary | 0010057: Crashes on startup after creating new project with empty template | ||||
| Description | When I start Ardour 9rc (either self-built from git 9.0-rc1-42-gde542e9d29 or the nightly Ardour-9.0.rc1.42-dbg-x86_64), creating a new project from an empty template or loading an existing session crashes on me about half the time. To debug, I built with -DDEBUG_EARLY_SCTS_USE which makes the executable built locally from git crash with SIGUSR2 being raised, the nightly download receives a SIGFPE. | ||||
| Steps To Reproduce | Run Ardour, select “New” and “Empty Template”, or open an existing session. | ||||
| Additional Information | Temporal::superclock_to_samples() attempts to divide by Temporal::superclock_ticks_per_second(), which is still zero. From the backtrace, it looks like motion events are being processed before Ardour is fully initialized, i.e. Temporal::reset() is called. | ||||
| Tags | No tags attached. | ||||

The backtrace with “git” in the name is from my local build, the other from the nightly. |
|
|
Weird. I open existing sessions countless times each day without issue, and create many new "empty" ones as well. it is unclear how that state can be reached without samplerate being set. What backend do you use? |
|
|
I build all backends but didn’t select one, so I assume it’s JACK. It may be a couple of factors coming together which abet the crash, for instance I haven’t been able to reproduce it if I cleaned out .config/ardour9 and didn’t migrate my old configuration. I’ll attach a tarball of my configuration directory, with this I could do run `Ardour9`, "New" -> "Empty Template" -> "Open" and confirm the warning about restricted lockable memory (this might or might not be related, I’ll have to log out and in again to check). |

In the meantime I could try it out with `ulimit -l unlimited` and couldn’t reproduce it there – also I was asked for the backend and selected JACK, so it is that. After `ulimit -l 8192` and confirming the respective warning dialog quickly, I could reproduce the crash reliably. If I waited a couple of seconds, it didn’t crash, so I guess it could be a race condition between initialization code and GUI handling running in parallel threads. |
