 Assertion failed with MacRuby Latest when use define_method. However,
 MacRuby r5271 works well in my environment.

 Test Script:
 {{{
 #!ruby
 class Foo
   # crashes with following cases.
   define_method(:crash_case1) {|a, b = nil|}
   #define_method(:crash_case2) {|a, *b, &c|}
   #define_method(:crash_case3) {|a, *b, c|}
   #define_method(:crash_case4) {|a, *b, c, &d|}
   #define_method(:crash_case5) {|a, b = nil, *c, d, &e|}
 end
 }}}

 Crash log:
 {{{

 Params[i]->getType()) && "Calling a function with a bad signature!"),
