+I debugged this, and the following seems to happen:
+- the crash is in the JIT when the JIT tries to compile the abstract
+method IPlugin:get_Name (). The call to the abstract method is made
+in an xdomain-dispatch wrapper, which is generated at marshal.c:2616
+in HEAD. Obviously abstract methods cannot be called with CALL.
+- That xdomain-dispatch wrapper is created indirectly by the code in
+mono_class_proxy_vtable. One interesting thing is that
+remote_class->proxy_class is MarshalByRefObject there.
+Lluis, could you look at this ?
