No. https://perl5.git.perl.org/perl.git/87058c31e9fa350bda8d797127c9c175d0b1a893 is the fault commit if I bisect it, but that commit just reveals/catches the mem overflow that was there since 2001 aka Day 1 of EU::C https://perl5.git.perl.org/perl.git/commitdiff/af6c647ee5aae2406b2bfb66c4fe11a81de75b05

Thanks for the patch, now applied, on CPAN (or in the pipeline) and in
blead.

As you say in the report, the bug is hard to replicate, and I wasn't able
to locally. Yes, the bug seems to have been present since the code was
first written, and your change looks to me to be the minimal and correct fix.
