Jarrett is right.  And it is REALLY difficult to narrow these things down. 
The problem is with these types of bugs, one seemingly unrelated change 
makes the whole thing start working, so I bet a lot of these types of things 
go unreported (as he said, who wants to paste a 25k line program to 
bugzilla?  It'll just get ignored).

Here is one I stumbled across while helping someone debug Tango's filesystem 
abstraction.  This is the smallest I could get it to (took me about 2 hours 
to narrow it down).  I'd really appreciate if Walter or whoever would fix 
this one:
