 could someone provide a small test case for this bug, that crashes MCS
 on Windows, and Windows only?

+The bug is really weird and needs:
+a) an access to a property as argument to a P/Invoke method
+and 
+b) the P/Invoke method needs to have non-positional parameters in the
+attribute.
+In the sample code, just delete the CallingConvetion stuff in the
+dllImport and it works, or delete the use of Raw and it works again.
+It maybe that mcs thinks all the non positional args are properties,
+while they can be fields, too (just a guess).
+
+The bug appears with the ms runtime, too.
