I checked in a fix.  Once tracked down, it turned out to be embarrassingly
simple and obvious:  During hygienic macro processing, at some point we
remove a Declaration from a ScopeExp.  Later on, we add it back to a scope.
(The same scope, but the same problem applies if it's a different scope.)
I failed to null out the 'next' pointer during the remove operation, so
when it later got added back to (the end of) the scope, we ended up with
a circular list of Declarations.  Oops.
