Re: [release] Boost 1.82.0 Release Candidate 1 is available

I have successfully built the RC in Ubuntu 22.04 and clang-15.

I'd like however to flag commit
https://github.com/boostorg/asio/commit/19cff007b0e9bf78dad921fe2a390d3458900f95
that was merged into Boost.Asio's master branch on the 5th of April
and hasn't gone into this RC as breaking existing code (concretely,
this prevents some Boost.MySQL examples from compiling). It was caught by chance
by a CI run. If this commit gets merged into any subsequent 1.82 RC, Boost.MySQL
(and potentially other user code) will contain flaws.

This commit breaks the following code:

// Token declaration
constexpr auto token = asio::as_tuple(asio::use_awaitable);
// In a C++20 coroutine
co_await socket.async_read(buffer, token);

I don't know if this was meant to be legal or not, but used to build
and run fine until yesterday.

I can provide a fix if this commit gets merged into any subsequent RC,
but other client code may get affected.

Regards,
Ruben.
