--- Comment #4 from Jonathan Bogdoll <j.bogdoll at gmx.net> 2010-12-03 11:28:58 UTC ---
I'm sorry, I mistakenly posted the first file twice.

The correct second file that is needed is as follows:

----------------- test2.cs --------------------
using System;

namespace Test
{
    public interface IExplorer: IGraph<ILocation>
    {
    }

    public interface ILocation: IEquatable<ILocation>, INode<ILocation>
    {
    }
}
---------------------------------------------

I also recompiled mono with -ggdb and -O0 to get a stack trace with line
numbers. Relevant fragment follows:
