menuitem->setEnabled() segv

[QtUsr001]

I have a main window with a layout. in the layout are 2 widgets. During my mainwindow initialisation i create the widgets, add them to the layout and call centralwidget() on the Layout.
The last thing I do in my mainwindow init is to disable practically all menu items except file/new. This all works as expected.

As part of file/new method I enable all relevant menuitems via setEnabled(true). Each one of these calls causes a segv for no apparent reason -- no additional debug info, debug console messaging or messages from static_assert are printed.

What is causing this?

hi
Have you tried to single step it to see if somehow you have infinite recursions?
Else its hard to imagine what could make it
crash since i assume it cant be a dangling pointer or the normal suspects.

ok I will follow up on that advice.

thanks.

I would like a written guarantee from you as to what menuitem is pointing to when you go menuitem->setEnabled() :)

I wouldn't expect a debug message for this, just a SEGV. But you should be able to sit in the debugger and break/traceback on the statement to see what it tells you *menuitem looks like.
