--- Comment #1 from Joe Loser <joeloser93 at gmail dot com> ---
`span` has a range deduction guide, but it is not properly constrained for
ranges satisfying `contiguous_iterator` concept only at
https://github.com/gcc-mirror/gcc/blob/01b5038718056b024b370b74a874fbd92c5bbab3/libstdc%2B%2B-v3/include/std/span#L412
per 22.7.3.3 in the working draft.

Sorry, typo in previous comment. The `span` range deduction guide should
constrain on `ranges::contiguous_range`, not `contiguous_iterator` concept --
sorry. This is from P1394 (https://wg21.link/p1394).

Johnathan, your fix LGTM. Safe to mark this as resolved, or do you need to do
something to backport it for the 10.4 release branch?

I.e. please don't mark it as resolved, I'll do that when it's resolved.
