Ruben, thanks for your feedback.

Yes, my example is intentionally kept minimal and simple to serve as a proof of concept.

As you see below, there are more complex integrations with Python/SWIG (RAPI, for instance), that also suffer from this problem:

They both compile and not segfault in Linux but crash in OSX, independently of their complexity.

As I don't have enough reputation to comment (I can only answer), I'll
answer by email.
First of all, I see your interface file is empty, except for the %module
directive. That shouldn't generate segfault AFAIK, but I'd put something
in there.
Second, I hope you'll be entering some body for the main in the .c file.
If Python is stupid enough to start running code in main(); - which it
probably isn't, but you never know - it'll segfault indeed.

So, put something in that interface file, add it to the .c file and post
again :)
