[fpc-devel] Unwanted finalization

[Yury Sidorov]

Hello,

The declaration of ITypeInfo.Invoke() is broken now anyway. Some of 
out parametrs should accept nil values and it is not possible with the 
current declaration. I doubt that ITypeInfo.Invoke() is used directly 
by user code. Especially in this broken form.

Can't you add an overloaded version to avoid breaking backward 
compatibility? Or does this problem occur all the time, so that it's 
better to break compilation than have people hunt all over the source 
code to find all possible problem locations?
