Comment:
Calling Ruby from Objective-C can be problematic because of the runtime
signature. In your case, the callWithInt: Ruby method is registered by
default as accepting an Objective-C object, but in the Objective-C side
you pass a C int, which results in the segfault.
We introduced an API called -performRubySelector:, we recommend to use it
when calling Ruby from Objective-C. Check out the MacRuby.h header file
for the complete list of these APIs.
