Your expectations are in violation to the standard ;-). The constructor is
selected by overload resolution. The non-template constructor A(const A& a)
would be preferred, if there would be a perfect match (e.g. if you had an
lvalue of type const A), but in your example you have an lvalue of non-const A.
The "perfect-forwarding" template constructor deduces to
template <> A(A& t)
via reference-collapsing, which is a better match for the argument expression
a.
So, this looks like an invalid issue to me.
