[Mono-dev] bug or wrong mono compilation?

[xplicit]

svn info

URL: svn://anonsvn.mono-project.com/source/trunk/mono
Repository Root: svn://anonsvn.mono-project.com/source
Repository UUID: e3ebcda4-bce8-0310-ba0a-eca2169e7518
Revision: 157507

Why dmcs could be not working in this case? When I change source code to

dynamic a=new object();
string s=a.ToString();
Console.WriteLine(s);

It works as expected.
