Is this a release blocker for 5.43.9?

While testing 5.43.9 tarballs prior to release, I encountered a  YAML::PP
failure related to Tie::IxHash.

We bisected the commits between 5.43.8 and 5.43.9 (not pushed) and found

# first bad commit: [b3f68b479c9876437620503fb7d54e14bceadcee] Convert
OP_CONST hash keys in key+val lists to HEKs

Should this block the  5.43.9 release?

Please advise.

Thanks,
-Eric


P.S.: Below you can find the bisect script:

#!/bin/bash

set -e
set -o pipefail

ORIG_DIR=$PWD
OUR_TMPDIR=$(mktemp -d /tmp/bisect-XXXXXXXX )
GIT_HASH=$(git rev-parse HEAD | fold -12 | head -n1)
PERL_PREFIX=${OUR_TMPDIR}/perl-$GIT_HASH

git clean -dxff
./Configure -des -Dusedevel -Dprefix=$PERL_PREFIX
make
make install

cd $PERL_PREFIX
BIN_PERL=bin/perl5*
BIN_CPAN=bin/cpan5*
