Description Atsushi Eno 2012-03-11 14:57:54 UTC
(Received a bug report from a local user: http://d.hatena.ne.jp/liner_lock/20110615/1308156678 )

The following code contains default argument, with incorrect method group reference. It compiles with mcs, but not with csc (verified with 4.5).

----
using System;
 
class Test{
 
   static bool Checker(int x,bool option = true){
      return x > 0 && option;
   }
 
   static void Testing(int x,Predicate<int> predicate){
      Console.WriteLine(predicate(x));
   }
 
   static void Main(){
      Testing(100,Checker);
   } 
}
