Description of Problem:
System.Reflection is broken for Nemerle again.


Steps to reproduce the problem:
1. Download, compile, and install Mono 2.2 to /usr/local/bin
2. Download a recent version of Nemerle (I tried with 0.9.3.99.8218 and
0.9.3.99.8160)
3. configure Nemerle to point at Mono 2.2 (./configure
--mono-from=/usr/local/bin)
4. run make


Actual Results:

A SIGABRT is received during compilation:

** ERROR:(class.c:3259):mono_method_get_vtable_slot: assertion failed:
(method->slot != -1)
Stacktrace:

Expected Results:

It should compile without errors, like it does with Mono 2.0.


How often does this happen? 

Every time.
