Then why did you configure with
PCRE_CONFIGURE_OPTS += --enable-newline-is-crlf
?? On Linux, as you say, newlines are just LF, but that configuration
specifies that lines are terminated with two characters (CR, LF). So a
single LF character will not be treated as indicating a newline.

For use on Linux, you need --enable-newline-is-lf, which is actually the
default. If you use --enable-newline-is-crlf, you will have to input CR,
LF in order to terminate the comment.

Specifying --enable-newline-is-crlf caused the difference, because your
test input contained NO "newlines", and a comment is terminated by
newline. So your comment lasted until the end of the regex.
