Hi Max,

We managed to figure out that OSProcess works when we use gcc <= 4.8 on Debian. We are happy to use 4.8 for now, so we're good. It would of course be super cool if we could use the series 6 gcc as that will soon ship with Debian 9 (stretch) but it's probably not trivial to just move to a new compiler version (as seems evident from the fact that a minor version change can mess up compilation).

Thanks for tracking this problem down and sharing the details. I came upon exactly the same problem with the Nix package and was able to work-around that by also downgrading to gcc 4.8. I am sure it would have taken a long time to work this out without the benefit of your experience.

Relatedly: Is there a suitable automated test that we can use to check that our VMs are basically okay? I am pushing the switch to gcc 4.8 to resolve this problem but I don't know whether this is causing other regressions or what other obvious problems I have missed. I'd love a bit of test coverage for the builds.
