I can reproduce the issue in Emacs 25.1 and newer, but not in 24.5
(configuration below signature), with the following modified recipe:

0. emacs -Q
1. (add-hook 'compilation-filter-hook
             (lambda ()
               (ansi-color-apply-on-region compilation-filter-start
                                           (point))))
2. C-x C-e
3. M-x rgrep RET
4. setq RET RET /dir/of/emacs/trunk RET
5. ...twiddle thumbs...
6. C-c C-k

Loading the 24.5 versions of ansi-color.el and compile.el in 25.1
between steps 0 and 1 does not seem to change anything.

Thanks,
