--- Comment #2 from Richard Smith <richard-llvm at metafoo.co.uk> ---
This program violates [temp.spec]/8:

If a function declaration acquired its function type through a dependent type
( without using the syntactic form of a function declarator, the
program is ill-formed.

The SHOW_ERROR case is ill-formed because it declares 'heck' with a dependent
type that is not non-dependently a function type. (Put another way, the
determination of whether a member-declaration declares a data member or a
member function is (permitted to be) made statically when processing the
template definition rather than when analyzing a particular instantiation, and
a declared member is only a member function if the non-dependent portion of the
type has a top-level function declarator.)

So I think this is not a bug.
