bug#45617: <query-replace> loses the edit region. Works in 23.3, broke in 26.3

[Bob Floyd]

It looks like the `replace.elc` file I've been creating isn't being loaded:

I changed:
(message "Replaced %d occurrence%s%s"
To:
(message "Replaced XX %d occurrence%s%s"

And the *Messages* buffer still shows:
Replaced 3 occurences

I've verified the elc file is re-written each time I change and
byte-compile-file replace.el.

Is there a command that shows the paths to the elc files loaded? Or, does a
new instance of emacs share elc's from an existing running copy of emacs
(that would be pretty geeky!)? I'm doing my tests with an emacs running for
several days now, assuming it would not interfere.

Yes, the correct place.  Maybe you need to compile it or just evaluate.
