--- Comment #5 from Reid Kleckner <rnk at google.com> ---
I think we can declare this fixed, but this issue is likely to pop up again in
other places because std::construct_at expects T*, and that requires casting a
pointer to uninitialized memory. The old way of doing this, placement new,
expects a void*. Adding a new CFI testing configuration for libc++ will be the
best way to detect such issues in the future.
