Even with this reproducer, I was unable to get it to happen on RHEL7 with
an unpatched bash-5.1 (en_US.UTF-8, de_DE.UTF-8). I was never able to get
it to happen using Frank's test case. It doesn't seem easy to reproduce.
As for patching the systems, I think this deserves being patched even
on stable distros. Albeit I would prefer that Chet released an official
patch first.
I did. The question is what the distros do with it. The example Frank
used -- Debian stable -- was 8 patches behind when he sent the report, and
is 12 behind now. Whether or not we think patches `deserve' to be applied
by the distros doesn't seem to count for much.
