dpkg --get-selections output for the 14.04 userspace
The execution environment is a 32bit Docker container with an Ubuntu 14.04
userspace (via Ubuntu Core project). The host is a 64 bit installation of
Ubuntu 16.04. The system kernel was recently updated from 4.8.1 to 4.9. Various
container packages were recently updated via `apt-get upgrade`.

$ valgrind --version

$ getconf LONG_BIT

$ uname -m

$ gcc --version

I will endeavor to switch the machine back to kernel 4.8.1 and gauge impact.
Valgrind works as expected on the 16.04 host.
