 I'm not sure if it's necessarily a compiler bug, rather I'm suspecting
something was changed in msys2's i686 gcc's. Based on my small findings, it
might be related to what “generic” means for -mtune for the 32-bit
compiler. I was asking around msys2's channels to see if anyone else could
reproduce it, but nobody has responded yet.
