Doug, Daniel,

OK, I have removed that, and the error as well as the segfault went away.

OK, thanks.

Is there any reason why I should use the current C API, instead of C++ ? 
I'd expect C++ to give me a much more structured API with a more 
fine-grained control over the preprocessing and parsing process, instead 
of having to pass options as string arguments. That almost looks like 
shell scripting ! :-)

Thanks,
         Stefan
