From 2ce7bf1ad5fd7aee21975b3dd1c8dceef3aab7e4 Mon Sep 17 00:00:00 2001
From: David Mitchell <davem@iabyn.com>

Subject: [PATCH] Perl_do_sv_dump(): handle PL_strtab
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When dumping this special hash, the values in the HE entry are refcounts
rather than SV pointers. sv_dump() used to crash here.
Petr Písař: Ported to 5.32.1 from upstream
a9bb6a62ae45bb372a5cca98a76d1a79edd89ccb.
