@Eli Ott: If this was my bug I would get the crash every time I quit the app and - best case - I wouldn’t get a crash but an exception.
That is plausibel and could be the reason why it does not occur when compiling the same project for Windows.
[quote=360730:@Eli Ott]Yes, very often.
You cannot generalize that. If it is an object you create, then checking for Nil will prevent crashing.
No. Most probably not.
You need to do that.[/quote]
I do this, still it crashes at random (and thats the odd duck… it happens random)
Also, how do you make sure the action event is finished when the user closed/quited the app?
It might seem to be random, and not anymore when you finally have figured out why it crashes…
A method or function also from a timer will always finish before the application is teared down by the OS.

You should save the crash report. Without it, I would have never been able with Eli and Jean-Paul’s help to find where it came from.
AFAIK nothing executes after the crash. In my case, since the app saved everything in CancelClose, it did not save anything when it crashed.
In a timer’s Action event one really has to test for each object to be Nil before accessing it.
What you also can do is set a flag in App, which in CancelClose is set to True if the app will close (meaning after you have asked the user). Then in the timer the first line always checks on this flag and returns immediately when it is True.

Ouch, ouch, ouch. I thought I had eradicated the crash, and sure enough, it is back. It does not seem to be just the same as before, though.

The last crash log you posted was the original one. The one you posted above is a totally different crash. Mouse related - NSTrackingArea _dispatchMouseEntered:?
What I do when I have a difficult bug is to stuff the app full of
theErrorLog.logitem currentMethodName
which write what the app is doing to a session log. Perhaps the users are doing something that you don’t (they usually do that). The “check timer if something is nil” was too simple an explanation. I still think that there is something wonky between Xojo and High Sierra.
Googling for [NSTrackingArea _dispatchMouseEntered:] lists a lot of Sierra and High Sierra related crashes (Illustrator, Affinity, SequelPro, etc.). The comments are usually screen-related, like “…when I switch monitors”, or “… when I switched to full screen mode”, or “… when I accessed the menu while the app was in full screen mode”.
Michel,
I am not very advanced in this area, but a random thought. Intermittent crashes might be related to different timing of thread events. Are you saving in the main thread?
Regards,
Phil
Sorry,
meant to add - are you sure all the other threads have finished before quitting?

This is about crashes, not about exceptions. UnhandledException is not triggered, as Michel has outlined very early in this thread:

Thank you Beatrix. I had fixed the first bug with the instructions of Eli, when sometimes, this new bug manifests. And this one is apparently deeper, since it does not relate to Xojo code.
I will try to put a log in each MouseEnter.

Hi Phil,
I don’t use threads other than main in this app.
In deed I have code in Unhandled Exception to handle errors and report them, but again, this one does not get trapped.
The hunt continues…
I’m seeing a crash on quit for all of my smaller apps built with 17r3. In each instance, a version of this crash report occurs:
0 com.xojo.XojoFramework 0x0000000102bd6baf RuntimeObjectIsa + 76
1 com.xojo.XojoFramework 0x0000000102be8c00 RuntimeViewDestructor + 91
2 com.tolisgroup.brutalk 0x00000001027ca48b Window.__Exit%%o<Window> + 11
3 com.xojo.XojoFramework 0x0000000102bd6a31 RuntimeUnlockObject + 815
4 com.xojo.XojoFramework 0x0000000102ae2812 RuntimeView::UnifiedClose(bool) + 598
5 com.xojo.XojoFramework 0x0000000102a6fa79 0x102981000 + 977529
Not the same thing that you’ve been seeing, but still happening on the call to Quit whether from the main Window’s Close event or from the Quit menu option.
There are several feedback cases and all are ignored because it is ‘random’ and not reproducable.
It is Xojo bug for sure - but not taken seriously. I pulled my hairs for this several times. It is über frustration.
Sam posted a fix (with declare) for this some days ago.

Could I ask you where he posted the fix ? Thank you.
Thanks @Christoph De Vocht and @Sam Rowlands - Placed Sam’s declare in the App.CancelQuit and the crash is alleviated.
I’m quoting it in this thread for posterity:
