Crash on launch on macOS in QAction::isEnabled()

Open ryandesign opened this issue 1 year ago • 5 comments

Hi, I'm the maintainer of tea in MacPorts and after attempting to update our port to 62.1.1 I found that when I launch it on macOS 12.7.1, it crashes immediately in QAction::isEnabled().

Here is the crash log.

I went back to 62.0.2 to which I had updated the port a year ago and it also crashes with the same message. I feel certain that I would have verified that the program opened without crashing before committing that update a year ago, though it might have been on an earlier major macOS version, and of course tea's various dependencies might have received updates in the past year which might be contributing to the problem.

And I should mention that this is a qt4 build with qmake, since I know you also have a qt5/qt6 build option with cmake.

Thank you for the bugreport! It's hard to me to determine where exactly is the error without debugger, and I don't have Mac/Mac toolchain for that. I suppose the error is hidden somewhere at the menu creation code, so I'll try to read it more carefully and possible I'll find where the error is.

It looks like it might be this uninvestigated Qt4 bug:

https://bugreports.qt.io/browse/QTBUG-25399

The proposed workaround there of disabling the native macOS menubar—

—works in that it no longer crashes but it drives your application so much further into "doesn't look and feel like a native macOS app" territory that I can't imagine any Mac user would want to use it that way.

Probably for MacPorts I need to just switch tea to use Qt5 at the expense of support for old macOS versions—or keep old macOS versions on Qt4 while using Qt5 for newer versions, if that's not too difficult for me to do.

Thank you! At 62.2.0 I hardoded Qt::AA_DontUseNativeMenuBar if Qt version < than 5, so at least TEA can run on Qt4/Mac build. Why Qt5, not Qt6?

Probably for MacPorts I need to just switch tea to […] keep old macOS versions on Qt4 while using Qt5 for newer versions

This is now done!

At 62.2.0 I hardoded Qt::AA_DontUseNativeMenuBar if Qt version < than 5, so at least TEA can run on Qt4/Mac build.

That will make the user experience terrible for those users who use Qt 4 on older macOS versions that were not affected by the bug.

Why Qt5, not Qt6?

Because I have years of experience with Qt 5 more or less working and no experience yet with Qt 6 and because I expect Qt 6 to have higher system requirements than Qt 5 and because you do not mention Qt 6 support in your qmake build system and it is easier for me to always use qmake than it is to sometimes use qmake and sometimes use cmake depending on the user's choice of Qt version.
