Comment(by lsansonetti@…):

 Looks like yet another ABI issue. llvm-gcc compiles the code as:

 define internal %struct.Foo* @"\01-[Foo
 %self, %struct.objc_selector* %_cmd, %struct.NSControl* %control,
 %struct.NSTextView* %textView, %struct.Foo* %words, %struct.NSRange* byval
 %charRange, i64* %index) ssp {

 In this case, the NSRange structure should be passed 'byval'. MacRuby
 doesn't (since sizeof(NSRange) is <= 128bit) but in this case the number
 of arguments seem to trigger something.
