Re: Need help debugging Phoenix in a application being migrated from Classic

This looks suspiciously like the seg fault I've been trying to isolate in
the Grid class.  I don't have a good minimal test case yet, but the error
occurs when I call wx._grid.Grid.CellToRect and the first thing reported is
this:

wx._core.wxAssertionError occurred
Message: C++ assertion "m_count > 0" failed at
..\..\src\common\object.cpp(352) in wxRefCounter::DecRef(): invalid ref
data count

then

wxAssertionError: C++ assertion "uiIndex < m_nCount" failed at
C:\PROJECTS\buildbots\win7-py27\dist-win64-py27\Phoenix\ext\wxWidgets\include\wx/dynarray.h(841)
in wxBaseArrayInt::Item():

​I'll try to get my debug build working so I can get a real stack trace
before I head out for the long weekend...​
