Qt Creator stops on a line but no fault or message reported

[SPlatten]

I'm using Qt Creator 4.8.1 based on Qt 5.12.0 (Clang 10.0 (Apple), 64 bit). I'm developing a multi-thread C++ application. Qt Creator stops on a specific section of my code with a yellow arrow pointing to a line. There is no reason displayed why it stops and no message logged in any of the panels.

Is there anything I can do to find out why it's stopping? The code looks fine, no errors and no problems that I can see.

@SPlatten What happens if you continue execution?

@SPlatten hi,

I hate to say it, but have you tried turning it of and on again?

Your Mac in this case. I run occasionally in similar situations when I do not do a roboot for a week or more.

@Jsulm, it just repeats the same, the arrow doesn't move and Qt Creator stops at the same line, it doesn't appear to move off.

@J-Hilk, Yes, I've been experiencing this for days now and I've powered down completely in-between.

I'm not sure why Qt Creator didn't report any error, however I've since discovered the source of the problem which was a bug in my code and fixed.
