PS: As additional information for posterity, there are various conditions that explain why this is/was only a problem on some specific distributions: * In addition to dwarves/pahole 1.24, binutils 2.40 seems to also be required for the problem to occur (in Arch, downgrading to binutils 2.39 fixes it). * Debian (and thus derived distributions) configures binutils with `--disable-x86-used-note`, which by default disables emitting the GNU notes which ultimately cause the .notes section to be aligned to 8 bytes. On Debian Bookworm & Ubuntu 23.04, the problem reproduces when building like: ``` export KCFLAGS="-Xassembler -mx86-used-note=yes" export KAFLAGS="-Xassembler -mx86-used-note=yes" make ``` Finally, here's a smaller .config to reproduce the problem on affected systems: https://zealcharm.com/20230416-btf-dedup-bug-sample-configs/minimal-repro
