[Message part 1 (text/plain, inline)]
As it turns out, the regex example files in question were originally downloaded as part of a regex course module... and were in DOS format (something that didn't occur to me to even check).  After running dos2unix on them, the end-of-line anchor was recognized as expected.

This bug report can be closed.

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.
