Thats a strange syntax for an identifier, anyway running it with sudo makes the segfault go away for me so I guess it's some permission problem.

Sudo doesn't help for me. It looks like it's getting into to the wrapped C function, then it segfaults when trying to read from the input buffer.

Edit: If you're interested in pursuing this further, please get in touch via my website, which is on my profile. Cheers!

I contracted you over the website.
