[Mono-dev] compiler method chaining

[Pete Erickson]

I've noticed a bug with mcs/gmcs with method chaining.  Below is a test 
case and sample compilations.  This test was with mono 1.2.6 preview 2 
(Mac OS X) but the same happens on 1.2.5 from debian lenny.

I tried submitting this to bugzilla but verifying my email address is 
apparently broken. 

Thanks,
pete
