Unit test for debug build?

[Regina Henschel]

Hi all,

Currently a debug build fails assert in SfxItemPool::PutImpl in 
itempool.cxx#679 if applying uno.FontworkSameLetterHeights or 
uno:ExtrusionToggle. I know how to fix it. But I don't know whether such 
fix has to be accompanied by a unit test and if yes, how to do it.

The problem is pure internal, the hash of SdrCustomShapeGeometryItem is 
not invalidated by the current implementation of above commands.

Kind regards,
Regina
