Hello Kjell,

I don't know exactly what happens... Besides Ibrahim says his UDF
works with stdcall...

But in theory, let's see:
- FB calls your "stdcall UDF"
- it saves return point, allocates memory for parameter references in
the stack (all parameters are passed by reference)
- processing goes to the UDF
- in the end, "stdcall UDF" removes the parameter references from the
stack and returns to FB
- then "cdecl FB" probably tries to remove the parameters references
from the stack once again?
Maybe Dimitry or someone else will clarify those steps, although it's
off-topic in this list.
