What worries me is the fact that it is so easy to mess up the heap. What 
other dragons are lurking ahead in 3.2.0?

For the record, I tried to set the codepage of the component to 'utf-8' 
and it still segfaults, so I don't think it's because of the default 
codepage.

Also the fact that some of the TFieldDefs.Add are procedure and some 
functions doesn't seem right.
