Building NObjectiveAST (an Objective-C++ parser written in C#) from
http://code.google.com/p/nobjectiveast/ leads to a runtime error about invalid

Reproducible: Always

Steps to Reproduce:
1. Check out NObjectiveAST code with the following: svn checkout
http://objcmapper.googlecode.com/svn/trunk/NObjectiveAST/ NObjectiveAST
2. Build the TestAST solution w/ MonoDevelop, commenting out the two lines in
Run.cs about changing the process priority, and fixing the hardcoded
backslashes in the path (or, ignore this step if on Windows).
3. Try and run TestAST.
Actual Results:  
Unhandled Exception: System.InvalidProgramException: Invalid IL code in
NObjectiveAST.Parser:GetNamespaceDeclaration (int&): IL_003f: ldelema
