--- Comment #1 from Philip Hazel <ph10@???> ---
Thank you for this report, which showed up a bad interaction between -o and -M
in pcregrep. It was looking for more matches "on the same line" - only after a
multiline match it hadn't realized it didn't need to. I have committed a patch
that fixes this - but sadly it was too late for the 8.39 release that came out
a few days ago. It will be some time before the next release, so I'm quoting
the patch below. The same bug was present in PCRE2, and I have fixed that as
well in the repository.
