Hi,
Good to know you're motivated to get into hacking MacRuby :D
`rb_marshal_load` is an "API", supposed to be used by extensions for example.
If you look in `marshal.c`, you'll see that the "load" method is defined by
`marshal_load` (without the rb_ prefix):
rb_objc_define_method(*(VALUE *)rb_mMarshal, "load", marshal_load,
-1);
This means that when a ruby code calls Marshal.load, it will call this method.
To sum things up, I think you just need to set a breakpoint to marshal_load,
not rb_marshal_load :D
Let us know how things work out!
