performSelector behaves oddly.

[rob@…]

Hi --

performSelector behaves a little oddly when you try to use it on the built ins of Ruby.

macruby-nightly > [1,2,3].performSelector(:pop)
ArgumentError: wrong number of arguments (-2055090267 for 1)
	from /Users/robertgleeson/Projects/Ruby/sinatra-effigy/(irb):1:in `<main>'

[1,2,3].send(:pop) works fine. In another case, performSelector() caused a seg fault but I can't remember what I did :-X

I'm only starting to learn Objective C and came across this when I wanted to see how Objective C methods worked from within MacRuby.

This is because #pop is implemented in C, and these functions do not conform to the objective-c calling ABI, yet.

[mattaimonetti@…]

The problem is still happening.

[lsansonetti@…]

Same problem as #664 I suspect.

Should be fixed in r4987.
