If this is really a cpu bug, why do they make this change windows-only? It's probably the only platform where they have enough users to be able to measure the crash, but shouldn't the fix be applied if building for x86 independent of OS? And the patch currently has an effect on Windows/arm where this CPU bug won't exist.

As far as I can tell it isn't a generic fix. They had two functions that always crashed on a misaligned read from __security_cookie so they added a patch that forces the alignment for these functions. Since __security_cookie seems to be a windows specific stack protection mechanism it makes no sense to apply the workaround on all systems. Someone correct me if I got that wrong.
