It seems unlikely as this shouldn't effect codegen. None of the other
bots seem to be red because it either. FWIW, my tests were 32-bit x86
on Windows 10 with MSVC 2015.

This was the only failure report I've received thus far, but I'll
definitely keep my eyes open to see if there's a pattern somewhere.
