Are these bugs with the gcc optimisations or the systemd source code, and if its gcc's fault are the problematic optimisations specific to a particular architecture (such as ARM)?  Just wondering if we can use overrides to only change the optimisations where they're a problem.

I am not sure how to isolate if it's an issue in the systemd source code but the issue is not present when using GCC 4.9.
Haven't checked if this is occuring on other architectures. Any feedback whether this occurs on other platforms (Raspberry Pi 2 is ARMv7) is welcome.
