Sebastian Guenther reported something similar.

Can you send me some source code, then I will try to debug it;
Probably there is still some conversion error floating around
somewhere in the system unit ?

Because none of the pointer routines seem to work on them. (Gives me type mismatches)

This will need some debugging, so some code that shows the problem would
be nice. Just writing a lot of output to the screen works fine here.
