+------- Additional Comments From bmaurer@users.sf.net  2004-12-26 00:24 -------
+This is happening because the compiler is assuming that any param is
+fixed. However, the pram is really a managed pointer, so the thing it
+points to may or may not be fixed.
+The problem is ParameterReference.VerifyFixed. But I don't understand
+the code here. I have no idea what the is_expression has to do with
+anything. Can someone add comments in the source?
