The issue seems to be same as https://github.com/Perl/perl5/issues/17154. It looks that we should rebase perl to the fixed version because the fix can't be backportable into perl5.30.

--- Comment #1 from Petr Pisar ppisar@redhat.com --- There is no fixed perl version. The latest perl version is 5.30.1 https://metacpan.org/release/perl and we deliver it.
We cannot apply the fix into Fedora 31 because it would break ABI.
We could apply the fix to Fedora Rawhide (32 now), but that would require rebuilding all Perl packages. However, I remember some discussions that there are some issues with the fix.
That means Fedora 31 won't receive the fix.

--- Comment #2 from Petr Pisar ppisar@redhat.com --- Unfortunately Fedora 32 is cramped system-wide changes that require mass rebuilding whole distribution and there is no time bootstrap Perl. Therefore this issue won't be fixed in Fedora 32. It will be fixed in Fedora 33 with regular Perl rebase to Perl 5.32.0.

--- Comment #4 from Fedora Program Management fedora-pgm@bot.bugzilla.redhat.com --- This message is a reminder that Fedora 32 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '32'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 32 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

--- Comment #5 from Ben Cotton bcotton@redhat.com --- Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
Thank you for reporting this bug and we are sorry it could not be fixed.
