--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Not a bug. The call to zzz.foo had to do overload resolution to decide which
foo to call. That means both result_of types get instantiated. That means the
lambda gets instantiated with an argument of int* as well as with an argument
of const int*. Without an explicit return type the body of the lambda is
instantiated, which fails the static_assert for the int* case
