Will queue that up for the next round of releases, using clang-20 on 5.4.y is brave :)
Just for the record, there is nothing clang specific here, it is a binutils problem. The clang-20 TuxMake containers just happen to have a newer copy of binutils from Debian Trixie after [1]. I would expect one of the updated GCC versions to reproduce the same issue, unless they don't build 5.4 for other reasons. I always try to ensure every stable version builds with latest clang so I would not consider it that brave :)
I plan to send a v2 addressing Segher's comments later today.
