And, as a further guess, the way $self->{ABSTRACT} is assigned its value, has something to do with it.
It's all very strange. I, in fact, did get to wonder whether the change was in the assignment of $self->{ABSTRACT}, and *not* in the behaviour of $self->{ABSTRACT} =~ m![[:cntrl:]]+! However, I didn't really look at how the former was being assigned. If I could reproduce the issue I reckon I'd be wanting to understand it. But I can't reproduce it ... so it's really not all that important to me. (I guess I just find it "intriguing" rather than "important".) To satisfy my own curiosity, I fiddled about with the following script, on both Linux and Windows: But it just outputs: on every perl I run it on. So I don't understand how a lone \r is being treated differently to a lone \n or \r\n in some cases for you. Cheers, Rob In reply to Re^5: 'perl Makefile.PL' warning for v5.20 to v5.24
