test code:

public class D {
  const D x = null;
  static public explicit operator int (D d = true ? x : x){
    return 0;
  }
}

dmcs fails with:
test.cs(3,57): error CS1041: Identifier expected: `?' is a keyword

csc (VS2010) succeeds with a warning:
test.cs(3,39): warning CS1066: The default value specified for parameter 'd'
will
        have no effect because it applies to a member that is used in contexts
        that do not allow optional arguments
