Rails - Jun 2006 - Where to report ActiveRecord unit test failures?

I just wondered - what is the policy on unit test failures in the  
ActiveRecord trunk?  Actually I''ve got two questions...

- is it normal for the trunk to fail unit tests, or is it always an  
oversight when this happens?

- if you notice test failures, what should you do to inform people?

Specifically, I''m testing a version of a patch that someone else has  
modified.  I just checked out the trunk and ran the unit tests on SQL  
Server to get a baseline before I applied the patch, but got 6  
failures and 4 errors.  I''m guessing that relatively few Rails  
developers use SQL Server so the tests are not run against it as  
often (we still use it at work for some stuff so I have access to a  
copy).  How do you get round the problem of different developers  
using different systems?

Or is the Rails team already hiding a big datacentre somewhere,  
running SQL Server, DB2 and Oracle enterprise editions checking that  
nothing ever breaks...
