Oh, I guess libc++ doesn't use `consteval`, but `constexpr`:

The macOS CI fails (as expected). Moving to draft for now, until someone clarifies the macOS clang situation. (I don't use macOS)

Most supported operating systems ship with clang-15 (or later), so bump the minimum to that and remove now unused workarounds for previous clang bugs.

For reference:

* https://packages.ubuntu.com/jammy/clang-15
* CentOS-like 8/9 Stream: All Clang versions from 13 to 15
* FreeBSD 12/13: All Clang version from 13 to 16
* OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (`clang16`); No idea about OpenSuse Leap

Responding to [https://petertodd.org/2023/v3-transactions-review](https://petertodd.org/2023/v3-transactions-review)

In general, I agree that RBF is a great fee-bumping mechanism. The entire point of v3 and EA is to make RBF more useful and less prone to pinning, and to enable us to use it in conjunction with CPFP while eliminating some of the inefficiency.

We seem to have entirely different perspectives about what RBF's limitations are today. Pointing out limitations in RBF is not intende

My bad, i ran the new `coins_db` introduced in #28216 for a while but not this one.. Will debug to find the other source of inconsistency.

Xcode 14.3.1 (currently used in the CI) is based on ~ LLVM 14. It's failing because removing the fuzz workaround requires LLVM/Clang 15 or later. The GH image ships with newer Xcodes, https://github.com/actions/runner-images/blob/main/images/macos/macos-13-Readme.md#xcode, so I assume we could switch to using Xcode 15.x + in the CI (based on LLVM 16.x).

The libbitcoinkernel `clang-15 libc++` job is also failing, so I guess this isn't actually fixed with clang-15, regardless of macOS?

You need to add the sanity check to trigger it.

If any version is going to be picked, shouldn't it be the one we use for releases?

Sigh... I'm tired of this target just doing random things. Turns out you can't perform the sanity checks because it's using a dummy backend where `Flush()` won't actually erase the cache. I'll just use a hack to avoid the crash in #28216.

Removed the use of a proper fix to simply abuse `Flush()` when the exception is hit to avoid the crash. See the first commit.

Xcode 15.0.1 (15A507) and 15.1 (15C65) versions are available now, and they are subjects for frequent updates.
