It looks that we should rebase perl to the fixed version because the fix can't be backportable into perl5.30. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ perl-devel mailing list -- perl-devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to perl-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/perl-devel@xxxxxxxxxxxxxxxxxxxxxxx
