--- Comment #2 from felix.huber@schyf.de --- Unfortunately, there is no free version, it's flexlm node locked. I also checked bug 41710 first, but it seems different. The issue started with the reworked clipboard functions of V1.9.19. It looks like IDataObject_AddRef is accessing fields in the IDataObject *data in the wrong way.
Can I do some tests, like dump the memory there the data pointer points to?
