From 6712a7b680bf5e88cf30a5251b90872418c320f2 Mon Sep 17 00:00:00 2001
From: Niko Tyni <ntyni@debian.org>
Date: Tue, 6 Dec 2016 13:56:46 +0200
Subject: [PATCH] Pointers should be long not int
Casting pointers to int types breaks on 64-bit platforms where Perl uses
memory areas with pointers over 32 bits, which seems to be the case for
PIE (position independent executable) builds.
This only touches the code path relevant to Debian; 5.8, 5.10,
and unthreaded code paths are intended to be unaffected.
The changes to thread dumping parts are untested as they are not covered
by the test suite.
