On windows, atty dereferences a potentially unaligned pointer.
In practice however, the pointer won't be unaligned unless a custom global allocator is used.
In particular, the System allocator on windows uses HeapAlloc, which guarantees a large enough alignment.

A Pull Request with a fix has been provided over a year ago but the maintainer seems to be unreachable.
