+Summary: When the identifier is forgotten, MCS raises an undiserable exception.
+
+Description of Problem:
+When you forget then identifier of a variable in a method declaration (e.g.
+"ref index" instead of "ref int index"), MCS should give only "error
+CS1041: Identifier expected", but it also raises an exception of type
+System.NullReferenceException.
+
+Steps to reproduce the problem:
+1. Create a method with a reference passed argument, but without the
+identifier of its type.
+2. Try to access a list using this argument as the index.
+3. Voilą, MCS raises a NullReferenceException.
+
+Actual Results:
+The error *and* the exception.
+
+Expected Results:
+Only the error CS1041.
+
+How often does this happen? 
+As I don't have a large test case, I could only test it on my current mono
+compiler.
