Gmane
From: Gilles Hamel <hamelg-QFKgK+z4sOrR7s880joybQ <at> public.gmane.org>
Subject: glibc memory issue
Newsgroups: gmane.comp.sysutils.backup.dar.support
Date: Sunday 1st July 2012 08:53:47 UTC (over 5 years ago)
Hello,

I upgraded to 2.4.6. Now I encounter memory fault on each backup. I
get this kind of message at random location, once per backup.
I have tried the configure flag --enable-debug-memory, but it doesn't
give valuable information.
How to get more information to troubleshoot this problem ?
