An investigation shows that commenting out HeapFree() in SysFreeString()
fixes all the problems with corrupted strings in that large and complex
application I have here. So, it appears that the problem is not that BSTR
cache corrupts its entries, but that strings get corrupted because they
don't get cached.

Before closing this bug as invalid I'd like to ask: Jacek, do you have an idea
how BSTR cache could be improved so that older strings get replaced by newer
ones once the cache is full?
