Re: [cffi-devel] Weird segfaults interfacing with libsane

I realise that that's not the sort of question for the cffi list, _but_ I wrote a trivial C program that I think should be equivalent and it doesn't die. I can't work out *how* libsane can work in one case and not the other (!) so I was wondering if anyone could make any suggestions. I'm attaching the two source files here.

The only difference I could spot between the C and Lisp programs is that version should be an :int, not a :pointer. (But that doesn't matter on 32-bit linux since they're the same size there.) In any case, it seems to work for me on Linux/amd64.

Have you tried running the program in other Lisps? CLISP and/or CMUCL, for instance.
