Hi,

I downloaded, compiled, and installed the September 15 snapshot, and tried
to compile the following (foo.cs):

  using System;
  class foo {
    public static void Main() {
      Console.WriteLine("Hello, World");
    }
  }

with this command:

  compiler.exe -L /usr/local/lib foo.cs

But I got an exception:

  Unhandled Exception: System.NullReferenceException: Value null was found
  where an instance of an object was required.
  at CIR.RootContext.IsNamespace(String name) in 
  c:\bjepson\src\mono-15-Sep-01\mcs\mcs\rootcontext.cs:line 568

  ...

The attached patch fixes this problem for me, by enclosing the offending
line in a try...catch block.  Once I did that, I had a foo.exe that runs
great and looks very nice with ILDASM.  Great work - this is very nice to
see!

Cheers,

Brian
