--- Comment #2 from Daniel Frey <d.frey at gmx dot de> ---
I'm using Ubuntu 14.04 in a VM, packages are installed from
http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu trusty main. Package
version is 5.1.0-0ubuntu11~14.04.1

Output from g++-5 -v:

Thread model: posix
gcc version 5.1.0 (Ubuntu 5.1.0-0ubuntu11~14.04.1) 

I'm compiling the example code with:

g++-5 -std=c++14 -O3 -Wall -Wextra t.cpp

I tried it without -O3 and it then prints the old output:

pure virtual method called
terminate called without an active exception
Aborted (core dumped)

So that probably means it has something to do with the optimizer?
