Scott,

This is not a bug, but simply illustrates why it is not a good idea to
mix hygienic and nonhygienic macros.  The identifier when is introduced by
test1, so any syntax objects you create with this identifier as a template
will be scoped where the definition of test1 appears.  This includes
(the copy of) thunk introduced by when.

Kent
