Package: clang-14 Version: 1:14.0.0-1 Severity: normal X-Debbugs-Cc: sedat.di...@gmail.com
Hi Sylvestre, User ldionne requests in [1] to integrate some important libc++ fixes: > We shipped LLVM 14 with an unfortunate regression in std::span which makes > adoption of LLVM 14 somewhat difficult in large code bases. > Long story short, some valid code won’t compile anymore, and while > workarounds exist, it’s a bit painful and it really shouldn’t be necessary > since the code is 100% fine from a user’s perspective. > This is my fault, I let that slip into the release, did not realize it was > going to have the impact it has, and my fixes missed the final RC by a couple > of days > Had I known the impact, I would have made this a release blocker. It's about these 2 commits: $ cd /path/to/llvm-project/git $ git log --oneline tags/llvmorg-14.0.0..release/14.x 3f43d803382d (HEAD -> release/14.x, origin/release/14.x) [libc++] Re-enable workaround for pre-ranges CTAD in std::span add3ab7f4c8a [libc++] Add workaround to avoid breaking users of <span> when <ranges> are disabled The changelog in [2] says nothing about an integration of these 2 commits. Unfortunately, an updated LLVM/Clang version 14 from <apt.llvm.org> is according to a lower Debian version only possible with some tricks.
