--- Comment #3 from Marshall Clow (home) <mclow.lists at gmail.com> ---
This code is ill-formed.

Section 18.5 [dcl.init] in the standard covers declarations, and paragraph 17
talks about the semantics of direct initialization (which is what this is).

It goes through a bunch of circumstances (none of which apply here) and gets
down to bullet #5, which says:
* Otherwise, if the destination type is an array, the program is ill-formed.

A simpler case would be:
    std::pair<int, int[2]> p { 0, { 0, 0 }};

which both gcc and clang reject.
