Awesome! Thanks for this.

The first thing I did was add the debugging string, which returned a negative number. Thanks for pointing out where in the original code the negative number was coming from.

Ultimately, replacing the NULL with "" did the trick and I no longer get a segfault!

Any thoughts on moving Inline_Stack_Vars to the beginning of the sub definition?

That sounds like something that would be worth filing a bug report about. What is your reasoning behind the prototyping?

Thanks for your help. If you have any more, general advice on writing a Perl wrapper around a C API I'd love to hear it. This is my first foray into trying to extend a C library so I've got a bit of learning to do :)

Thanks again for your help!
