--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
I believe the warning is intended here (child1 and child2 have external linkage
but their base classes are specializations of templates that depend on (the
address of) objects with internal linkage (constexpr).  That could cause
problems as described in the GCC manual under the -Wsubobject-linkage option.
