For what it works, it also works for me with grep 3.1 running on RHEL 
8.5, in the C locale.

One possibility is that 'grep' is a user-interposed shell script that is 
adding some options of some sort. Or perhaps the GREP_OPTIONS 
environment variable is set to something squirrelly in the environment 
(this environment variable was dropped in grep 3.6 partly because of bug 
reports like this one).

The user can determine this by running the shell commands "type grep" 
and "env" and inspecting their outputs.
