Can't debug with Qt 5.12.2 on Windows

kitfox

I recently installed the 5.12.2 release for Qt on my Windows10 machine. Unfortunately, the debugger keeps halting whenever I try and run a project in debug mode.

I've created a brand new Qt with widgets project via the new project wizard. When I set my Build & Run under Projects to use Desktop Qt 5.11.2 MinGW 32bit, there are no problems and an empty main window is displayed onscreen. However, if I switch to Desktop Qt 5.12.2 MinGW 32bit, the main window is not displayed and the debugger hangs on disassembled code within widgets/qwidgetanimatior.cpp. Same with the 64 bit version of MinGW.

Is there a way to get this working?

@kitfox Can you please show the output of Windows > Views > Debugger Log? Thanks.

I've posted the log:

@kitfox It seems QWidgetAnimator::abort(QWidget*) is called, otherwise I don't see anything strange in the log.

Can you actually run the program (without debugger)?

kitfox

Yes, I can run it through the IDE with the Run command.

@kitfox I think you should file a bug at bugreports.qt.io - and please add a link here.

I honestly have no idea what's going on.
