I don't understand the issue either. The code behaves the same way for me
regardless of the line ending in test.txt.
Can you provide a simpler example, please?

I don't really understand the issue you have from your example, but in general
LF is the compile-default linebreak for PCRE. If you want to use a different
linebreak character you can either compile PCRE with the appropriate option or
specify a control option like (*CRLF) before your regular expression.
