Correct syntax to register object reference using qRegisterMetaType?

so perhaps this is something that needs looking at?

This means that there is a thread context switch somewhere even you tell us it isn't.

@Christian-Ehrlicher , Well that's the only change I'm implemented and now there is no message, so perhaps this is something that needs looking at?

Run with QT_FATAL_WARNINGS=1 as an environment variable and extract the stack trace, then you will have leveraged your debugger to show you exactly where you're passing a reference between threads.

QT_FATAL_WARNINGS=1

I've opened both .pro files and added that line, then cleaned and rebuilt, the applications have been running for several minutes, nothing to report, no issues.

It's an environnement variable, not a define.

You have to set it in the Run tab of the Project panel.

SPlatten

@SGaist , Yes, just googled it and then added as environment variable:

export QT_FATAL_WARNINGS=1

Then restarted, same, not seeing anything additional.

SGaist

Restarted what ?
How are you currently running your application ?

SPlatten

@SGaist , I launch the processes with Qt Creator in debug mode, using two separate instances of Qt Creator.

SGaist

Did you check the environment variables in the Run part of the Project Panel to ensure it's properly set ?

SPlatten

@SGaist , I checked in a terminal, I don't know how or where to "Run part of the Project Panel" ?

Easy to find actually.
Left pane: Projects -> Build & Run -> Run...
