 Please describe your problem with more details. Feel free to add a sample code to reproduce the issue.

BTW are you building VTK with DEBUG_LEAKS=ON ?

 vtk 5.0.2 library was builded as shared lib, debug mode and no DEBUG_LEAKS option.
MFC program is generated with standard MFC SDI application in visual studio .net 2005.
then included some vtk header and created new class and deleted it
CsampleView::CsampleView()
{
    // TODO: add construction code here
    vtkRenderWindow* renWin = vtkRenderWindow::New();
    renWin->Delete();
}
when MFC sdi application is builded with "Use MFC in a Shared DLL"
following error occurs.

sample.exe': Loaded 'C:\WINDOWS\system32\IMEKR70.IME', No symbols loaded.
'sample.exe': Loaded 'C:\WINDOWS\system32\uxtheme.dll', No symbols loaded.
Detected memory leaks!

but in "Use MFC in a Static Library"
there is no error.

I have attached sample code.

 That output log is reported in front of vtkInstantiatorHashTable::~vtkInstantiatorHashTable.

I thinks class name is deleted after MFC report.
That will be because of the dynamic link.
