how very fittingly at that:

Rich, you had reported *this very bug* one and half years ago, for
upstream glibc. "Small world" and all that. They fixed it for 2.35.

Apparently, the fix has not been backported to RHEL-9 to this day. My
version (in RHEL-9.1) is "glibc-2.34-40.el9_1.1.x86_64", but looking at
the latest RPM in brew (glibc-2.34-68.el9, for RHEL-9.3), that one is
still not 2.35-based, and the %changelog does not indicate the patch
from <https://sourceware.org/bugzilla/show_bug.cgi?id=28256#c2>.
