--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Confirmed, reduced:
#include <initializer_list>
template<class T>
struct A { A(...); };
template<class T>
A(std::initializer_list<T>) -> A<T>;
A a{1,2,3};
This seems valid according to [over.match.class.deduct]/4. In order for the
initializer-list phase of overload resolution to kick in the class template
doesn't necessarily need an initializer-list constructor, it suffices to just
have a guide that looks like one.
