The full build log is available here [1].

The issue is due to ISO C23 declaration of bsearch, memchr, strchr,
strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr,
which now returns a pointer to a const-qualified type when the input
argument is a pointer to a const-qualified type [2].

I would like to thanks Emanuele Rocca for doing the archive rebuild on
a fast arm64 server.

Regards
Aurelien

I confirm that. It's not clear to me why the rebuild was done against 
this version while the version in unstable is supposed to be 
20260109-1~exp1 for more than 40 days. And I have a second build log 
from 3 days ago, done on a different machine, different architecture,
running in a different country, and using directly deb.debian.org, that 
exhibits the same issue. And the corresponding build log with glibc from 
unstable also exhibits the same issue...

It's not clear to me what happened, but sorry about the broken bug 
report. I am therefore closing it.

Regards
Aurelien
