--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
This is fixed on trunk, apparently via bug 64667.
Unfortunately, the warning in the reference and pointer cases is missing a
caret (see below), and in the member case points to the constructor rather than
to the member initializer. The following patch fixes the location information.
I'll submit it shortly.
