--- Comment #3 from Nathan Sidwell <nathan at gcc dot gnu.org> ---
The problem is that in a local name 'Z fn E name [disc]', 'name' could be a
(nested) function and have encoded parms.  We do not expecting that and either
barf or attach them to the wrong level of the tree.  Attaching to the wrong
level works most of the time, except when the fn is an instantiation.  And of
course, generic lambdas are such a thing and didn't prevously exist.
