You've got 6 supressions, while I've got 3. Could be that errors I see are
hidden from You.
Try running with
valgrind -v ./a.out
I've re-worked the application to work with only one lvm2 handle and it's
been stable for the past 17h while with multiple lvm2_exit()'s called it would crash
after 2-3minutes...
> What version of lvm2 are you using?
lvm2 2.02.96-2
gcc-multilib 4.7.1-1
valgrind 3.7.0-2

It is vanilla upstream source, Archlinux package doesn't use any
distro-specific patches, it's compiled with
./configure --prefix=/ --sbindir=/sbin --sysconfdir=/etc --localstatedir=/var --datarootdir=/usr/share \
--includedir=/usr/include --with-usrlibdir=/usr/lib --libdir=/usr/lib --with-udev-prefix=/usr \
--with-systemdsystemunitdir=/usr/lib/systemd/system --enable-pkgconfig --enable-readline \
--enable-dmeventd --enable-cmdlib --enable-applib --enable-udev_sync --enable-udev_rules \
--with-default-locking-dir=/run/lock/lvm
make
