System.AccessViolationException in QBoxLayout destructor

[TripleWhy]

Consider the following code:

var vbox = new QVBoxLayout();
var hbox = new QHBoxLayout();
vbox.AddLayout(hbox);
vbox.Dispose(); // System.AccessViolationException

Tested with the official QtSharp-0.7.4 release with Qt-5.9.2-MinGW. The equivalent code in C++ runs just fine.

@TripleWhy thank you for your sample. I'll try it and see if I get the crash myself.
