I have proceed further and found that the problem is with the compiling
of long (19 digits) constants as in the following fragment of code

//
// expression.cs: Expression representation for the IL tree.
//
// Author:
//   Miguel de Icaza (miguel at ximian.com)
//   Marek Safar (marek.safar at gmail.com)
//

        using System;

        //
        //   Unary implements unary expressions.
        //
        public class Unary { //   : Expression {

                void TryReduceConstant ( )
                {
                  ulong  long_constant = 9223372036854775808; 
                }

        }

I tried to compile the above code under Mono 2.0 RC1 and SVN mono-112691 trunk.
The results, in fact, are the same:

$ MONO_PATH="/home/user002/mono-112691/mcs/class/lib/monolite:$MONO_PATH"

Constants with 18 digits, like 922337203685477580,  are handled well:
