+Summary: Delegate equal operator
+
+The == operator produces an unhandled exception when a != null and b == 
+null.
+
+FIX:
+
+file: /mcs/class/corlib/System/Delegate.cs
+lines: 290 ~ 295
+
+if ((object)a == null) {
+    if ((object)b == null)
+        return true;
+    return false;
+}
+return a.Equals( b );
+
+Should be:
+
+if ((object)a == null) {
+    if ((object)b == null)
+        return true;
+    return false;
+} else if ((object) b == null)
+    return false;
+return a.Equals( b );

+- }
++ } else if ((object) b == null)
++    return false;
