We see that with v5.10.y, v5.15.y, and v6.1.y when building ChromeOS images with clang/lld. There are additional problems with LTO and the built-in assembler. See https://www.linuxquestions.org/questions/slackware-14/error-building-kernel-6-1-44-on-current-with-clang-4175727865/ for a summary.
As far as I can see none of those problems has been fixed in the upstream kernel.
