You noticed
==7941== Memcheck, a memory error detector
==7941== Copyright (C) 2002-2010, and GNU GPL'd, by Julian Seward et al.
==7941== Using Valgrind-3.6.1 and LibVEX; rerun with -h for copyright info

--7941-- Valgrind options:
--7941-- --suppressions=/usr/lib/valgrind/debian-libc6-dbg.supp
--7941-- --malloc-fill=aa
--7941-- --read-var-info=yes
--7941-- -v
--7941-- --track-origins=yes
--7941-- --log-file=/tmp/lily.log
in the valgrind log file I posted? The malloc-fill made no difference,
by the way.
