confirming that upgrading zlib1g with
zlib1g_1.2.7.dfsg-13~nd12.04+1_amd64.deb
backport built from wheezy's version

resolved a segfault and the valgrind complaint ;)

I would still be too cautious to just upgrade to it since it might cause
heavoc:

according to http://upstream-tracker.org/versions/zlib.html
at least 1 symbol was remove in 1.2.7
BUT if you are really keen on doing that:

I have uploaded this build to "-devel" neurodebian archive which is not
publicly announced, but accessible.  So if you are keen on trying:

wget -q -O- http://neuro.debian.net/lists/precise.us-nh.full  | grep -v 'data' | sed -e 's,debian ,debian-devel , g' | sudo tee /etc/apt/sources.list.d/neurodebian-devel.sources.list
sudo apt-get update
sudo apt-get install zlib1g

at least you should still be able to downgrade to the older/buggy version
if things would go wrong ;)
