Hm.  If you'd just showed this one, my thoughts might bend towards a bug
in our sort abbreviation logic, which is relatively new ...

... but this stack trace is not going anywhere near that code.  The
common factor is just strcoll_l(), raising the possibility that you're
dealing with a glibc bug, or perhaps corrupted locale data on your
machine.  Are you up-to-date on glibc patches?
