This is tracked as issue https://bugs.launchpad.net/bugs/1304754 but at this time is not marked fixed released.
We work around this in CI with this PPA
ubuntu@winton-09:~$ cat /etc/apt/sources.list.d/ubuntu-toolchain-r-ppa-trusty.list deb http://ppa.launchpad.net/ubuntu-toolchain-r/ppa/ubuntu trusty main # deb-src http://ppa.launchpad.net/ubuntu-toolchain-r/ppa/ubuntu trusty main
However in the case of released builds of Juju, this workaround is not available as the LP builders do not use this PPA and are building from the outdated compiler version.
