7.4.1 backend crashing - Mailing list pgsql-cygwin

I've got a fresh install of cygwin and 7.4.1.  I was doing a little
exploring today and tried the following query from psql:

select * from pg_stats

I get a message saying that:

Server closed the connection unexpectedly.
    This probably means the server terminated abnormally
    before or while processing the request.
The connection to the server was lost.  Attempting reset: Succeeded.

Is this a bug, or expected behavior?

Just Curious,
Mark
