Segmentation fault when exiting when linked against Qt 6.9.1

Ah okay. So no 6.9 backport? I just wondered, because in the respective "Change ID" https://codereview.qt-project.org/c/qt/qtbase/+/653727, it's listed: "Fixes: QTBUG-137755 Pick-to: 6.10 6.9"

@l3u_ Yes, it looks like it was cherry picked to 6.9 branch, so may end up in some 6.9.x version :-)

The fix will land in 6.9.2, which we plan to release on August 14th.

If you want to cherry pick and compile locally, please make sure to pick the following 5 commits in the right order:

Nice :-)

I just tried it locally, cherry-picking the exact comments you linked. Worked without a collision on a v6.9.1 checkout.

And – you may already have thought that – I can confirm the segfault is gone now, also for my quite complex use-case :-)

Great that you are using dock widgets! As you may have suspected: QDockWidget is slightly closer to my heart than other creatures in the widget zoo ;-)

First, it was just a QTabBar interface. But over the years, it got more and more complex, and at some point, I learned about QDockWidgets – and I loved them at first sight ;-) The same as the tab bar if you want – but way more if you need it. The possibility to arrange them as you like and need is really nice. This is actually a powerful tool, with a great user experience. QDockWidgets really rock! They do, from time to time, cause some headache (this is actually not the first bug I filed about them ;-) – but they are really cool.

@l3u_
Could you mark this thread as solved, please?

@Axel-Spoerl Love QDockwidget too, great work <3

I always miss them in QML ( i know that QML is mainly mobile focused but nevertheless). :D

Axel Spoerl

@StudentScripter Not as an immediate priority, but we are planning to implement something like dock widgets also in Quick Controls.

StudentScripter

@Axel-Spoerl Awesome <3 Is it on the near roadmap or will have to wait a few years?

@StudentScripter Just so you know, @Axel-Spoerl is away atm and won't answer for a week or two...

StudentScripter

@JonB Thanks for the hint, but im in no hurry right now. :D Have a nice day.
