Why don't you use PTK.

It's available at www.headrush.co.za and is designed for just this task.

Its open-source btw.

yes, when building a wrapper for the Sablotron library using CDECL
procedure and PChar Parameters . 
As far I remember, mine was due to the fact that I must managed a string
variable outside of a 
callback procedure  and not as a local variable when converting it to a
PChar passed to another 
procedure of the library. When not doing this the result were not the same
every time and I have 
sporadic memory violation error depending on the size of the string and
others strange issues. 
Hope this helps,
