I have two comments: The .* matches to an emtpy string, so it can match to the position of "\r" in a "\r" string. The length of the match is 0, so it does not match to the "\r" itself.
The PCRE2_DOTALL option allows dot to match to a newline.

It's hard to say without any testdata; could you please share some examples of the patterns that you're using, and the corresponding subject strings that seem to match at unexpected places?
