Subject: Re: Re: Bug#1068350: musl: miscompiles (runtime problems) on riscv64 and s390x with static-pie → seems to be a toolchain bug
after all, it does too hit glibc

I don’t think so?
In <Pine.BSM.4.64L.2404042102310.18654@...c.mirbsd.org> I already
posted the short version; the actual source is (mirrored):
The initcoms array is here:
https://github.com/MirBSD/mksh/blob/b0219da8e6dfc7b16e923e220dc6933c5ed9b326/main.c#L77
Tdr is defined at:
https://github.com/MirBSD/mksh/blob/b0219da8e6dfc7b16e923e220dc6933c5ed9b326/sh.h#L3055
The u_ops array is declared a few lines above that and defined at:
https://github.com/MirBSD/mksh/blob/b0219da8e6dfc7b16e923e220dc6933c5ed9b326/funcs.c#L160
initvsn is defined at…
https://github.com/MirBSD/mksh/blob/b0219da8e6dfc7b16e923e220dc6933c5ed9b326/sh.h#L713
… with the EXTERN and E_INIT macros from…
https://github.com/MirBSD/mksh/blob/b0219da8e6dfc7b16e923e220dc6933c5ed9b326/sh.h#L657
where main.c defines EXTERN, so the string is embedded into the file using it.
Is there perhaps a misunderstanding with the gcc/binutils/glibc developers
as to what static-pie is meant to be?

<hecker> cool ein Ada Lovelace Google-Doodle. aber zum 197. Geburtstag? Hätten
die nicht noch 3 Jahre warten können? <mirabilos> bis dahin gibts google nicht
mehr <hecker> ja, könnte man meinen. wahrscheinlich ist der angekündigte welt-
untergang aus dem maya-kalender die globale abschaltung von google ☺ und darum
müssen die die doodles vorher noch raushauen
