In the past I've noted a lot of change for the sake of change. Not to say it is the case here, ... Yes, I don't think it's the case here. There's good evidence that this change was deemed necessary. However, I've just built perl-5.33.8 on Windows, without -fwrapv, and all tests passed. This was using gcc-10.3.0. Maybe Windows was never affected, or maybe something has changed with gcc-10.3.0. I'll test more extensively with perl-5.33.9 when it comes out (either later today or tomorrow), and add a report to https://github.com/Perl/perl5/issues/13690 if I can't find any need for -fwrapv Cheers, Rob
