    Description

      Adding items to GridLayout through default property alias causes a crash when destroying the item.

      To reproduce:

      • use Qt 5.6.0 MSVC2013 or MSVC2015 64bit build on Windows 10
      • start attached application
      • close the window

      I could not reproduce this with MinGW on Windows 7 or 10 and also does not seem to be reproducible on Linux.
