Proposed Boost.AFIO has been generating this assertion fail for some time on
clang's >= 3.4 on ARM and Windows that I know of. I had simply been recompiling
clang with assertions disabled or falling back to clang 3.3 and all is well,
however I saw Chandler at C++ Now last week and he got annoyed with me for not
reporting it. So here it is.

I see a number of bug reports with this exact same assertion fail. I'll link
them shortly.

On Windows using the binaries for clang 3.6 from the LLVM website:
