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.</div>

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.<br>
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.<br>
