Description
Re-docking a QDockWidget often causes a crash in the 5.3.0 release on OS X.
To reproduce:
- Undock either of the docked widgets in the qtbase/examples/widgets/mainwindows/dockwidgets example by dragging or double-clicking the widget's titlebar.
- Re-dock the widget by double-clicking its title bar.
This almost always causes the application to crash within 10 attempts with one of the following reports:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: EXC_I386_GPFLT

These look similar to the crash from QTBUG-39026: Regression: Qt Creator spurious crash on "Add New Header File".
