Debian stable, with a bunch of stuff from backports, and some from
unstable. From gcc -v:

gcc version 4.9.2 (Debian 4.9.2-10)

Thank you. The reason that I thought that it might not be a compiler
bug is because of the claim here that it can also be caused by a build
system that isn't designed to be run concurrently:

So I'll have to decide whether to report against kernel-package, gcc,
or not at all.
