Are you able to bisect this by any chance?
I think this is the runtime manifestation of https://github.com/ClangBuiltLinux/linux/issues/2116 when built with a version of LLVM without assertions (when assertions are enabled, the build just fails). I can reproduce this with a version of LLVM that contains the broken change and it is resolved with a version of LLVM that contains Fangrui's fixes. I assume this should hit LKFT in the next couple of days via apt.llvm.org.
