--- Comment #7 from Jason Merrill <jason at gcc dot gnu.org> ---
This is due to my PR53220 change to discourage use of compound-literals in ways
that produce a dangling pointer when the C++ compiler treats them as prvalues,
unlike C where they have variable lifetime.

I think the change was always wrong, but wasn't really a problem until we added
array prvalues in C++17.
