I have been trying to find out, why it works on your computer and not on mine.

It turns out, that it fails with fpc 1.0.11 (5-3-2004) and works with fpc 1.9.3
(10-3-2004). Windows and Linux versions behave the same way (failure with fpc
1.0.11 and success with fpc 1.9.3).

In both versions I am using process.pp version 1.19.

Do you have a clue, what might cause these different behaviour?

Compiling with 1.9.3 is not a option at the moment, because I need to be able to
use a debugger and debug info is still not working right.

TIA,
Vincent.
