OSX AbstractListModel Model Destructor Called

I have not reproduced this on any other platform, only OSX.

But the usage of AbstractListModel and beginResetModel()/endResetModel() is not stable on OSX.

Qt is calling the overridden AbstractListModel destructor.

I my case, my class override name is Trpzmodel, so when I look at the exception stack trace, I see the stack show a route through a model destructor, but NOWHERE in my code is there such a call, explicit or implicit to destructor.

Now, I load my model in QML using an INVOKABLE:

Q_INVOKABLE Trpzmodel* gmodel(const QString& gsmodel) and it works fine in qml:

Listview

{ id: glist model: Rpz.gmodel("TESTMODEL") delegate: etc.... }

When I call, this->beginResetModel() and this->endResetModel() during list repaint operations, I trigger the following exception:

testalert(1543,0x7fff72265000) malloc: *** error for object 0x7fff5fbff568: pointer being freed was not allocated

• • • set a breakpoint in malloc_error_break to debug

Since I only allocate the models at the beginning of the program ONCE and are never destroyed.

When I comment out (this->beginResetModel()/this->endResetModel()), the program no longer throws exceptions but the list is NOT updated.

There must be a way to cause the ListView to repaint in a safe way.
