--- Comment #6 from Julien Nabet <serval2...@yahoo.fr> ---
I traced the number of calls to constructor and destructor.
For ChartModel, it's ok, same number
It's wrong for UndoManager, I only see calls to its constructor, none for
destructor.
The use of UndoManager in ChartModel is:
::rtl::Reference< UndoManager > m_pUndoManager;
(see https://opengrok.libreoffice.org/xref/core/chart2/inc/ChartModel.hxx#133)
I noticed destructor of ChartModel is:
196 ChartModel::~ChartModel()
197 {
198 if( m_xOldModelAgg.is())
199 m_xOldModelAgg->setDelegator( nullptr );
200 }
But then I'm completely lost since I don't know enough about rtl::reference,
weak ref, acquire/release, dispose/disposing to help here.
