Crash when using sidebar / macOS 14.0 / M1

System: macOS 14.0
Arch: M1 arm64
MiniZincIDE: 2.7.6

MiniZincIDE crashes often when I'm using the project sidebar.
The most common case is when I want to open an .msc (compiled model checker file).

Would you be able to attach an example project and steps to reproduce? Or if you can't publicly share it, you can e-mail it to support [at] minizinc.dev. I haven't seen any crash from opening compiled checkers from the the project sidebar on macOS or on Windows so far.

Sure, previously I thought it was my setup responsible. But my students using macOS 14.0 are having the same issue.
It is sad to see students coping with issues of this kind...

Here you have my repository (second lesson in Constraint Programming course) https://gitlab.com/agh-courses/23/cp/lab-02 .
How to reproduce:

open the project: lab-02.mzp
play with the sidebar for several seconds, try to open some files, check directories, etc.

Unfortunately I still can't seem to reproduce this (on an M1 mac running macOS 14.0).

Were you able to trigger this on a fresh clone of the lab-02.mzp project? I've tried opening/closing every file (model, data. checkers) and running each of them and combinations of them using the project panel, and it hasn't crashed so far.

I've been able to reproduce it on the fresh clone.
my students (using macOS) also had the same issue.

Is there any preferable way to gather logs to send you?

Here is an output from terminal.

Another short update.
I've built MiniZincIDE from the master branch, and I can't reproduce the issue via my build.
The official 2.7.6 still crashes...

What version of Qt did you use to build? The official build used 6.5.1, so maybe this is actually a Qt bug which got fixed later. Although that still doesn't explain why I can't reproduce this using the official package.

I've built it against Qt 6.5.2

Hmm... I've removed all the MiniZinc related settings:

rm /Users/msl/Library/Preferences/org.minizinc.MiniZinc*

Since then, I can't reproduce the issue.
Sadly, I have no backup of the settings files…
Will ask students having similar issues about their settings.

As I cannot reproduce it consistently, I close the issue :)

OK, the issue came back again. I would debug it by myself, but... it does not happen with my own build from the master. For now, I assume it may be related to the different qt version used in the builds. I will come to this after the next release.

Would you be able to try this build? This has been built by our CI system using the latest stable Qt, so if the issue persists here then we'll have some more investigation to do.

It seems fine… I cannot reproduce the crash, will try harder in my spare time and then come back with some results ;)

BTW It's great OR-tools got into the bundle :)
