Thanks. Downgrading gawk fixed it for me too.
sys-kernel/gentoo-kernel and sys-kernel/vanilla-kernel do fail too with this gawk

Created attachment 803497 [details, diff] UPREF patch for double free detected in tcache 2 Wouldn't it be better to apply this small patch instead of masking it? Source of the patch: https://mail.gnu.org/archive/html/bug-gawk/2022-09/msg00011.html cheers.

No worries and it was a fair question :)
After trying the patch for perf (see #868522) I decided to also try a kernel build. This was successful: I just built the "all" target (vmlinux, modules, bzImage) for my BTF-enabled config without issue. Looks like the patch works.
I decided to take a peek and see what happened here in the meantime. Apparently the attached patch helped, but not completely; it was applied but later reverted: https://mail.gnu.org/archive/html/bug-gawk/2022-09/msg00056.html Commit with lots of other stuff (changelog, tests etc.): https://git.savannah.gnu.org/cgit/gawk.git/commit/?id=2848045aed5ccfd7b582808288f7fcc18d319952 That patch turned out to need another one: https://git.savannah.gnu.org/cgit/gawk.git/commit/?id=3d7178e78e523574649578593192bab2e0d08a2a Decided to put those to the test..and with the original patch removed and those two applied, gawk again fails to build perf (#868522). :-( Seems like this will stay masked for a while.

Thanks for the update, I've been following on the ML and was considering posting something here for the people who wonder why we don't just apply it. But I hadn't tried any of the patches... oh dear! Maybe mention it on bug-gawk?
(In reply to Holger Hoffstätte from comment #15) > Decided to put those to the test..and with the original patch removed and > those two applied, gawk again fails to build perf (#868522). :-( Apologies - this turned out to be a pilot error: both patches together seem to work and both kernel & perf build without issue. So it looks like 5.2.1 will be fine.
