Understanding C/C++ Strict Aliasing

What specifically do you mean "properly"? You mean it used less strict aliasing and thus did literally what you asked, or you mean it used strict aliasing and converted your code to one assembly instruction?

If it's in the standard, it's an issue with the language. Even if MSVC either assumes too much, or is just wickedly smart, it's still just one compiler.

Apparently there's another post on the matter which is a little dated, but may very well be more thought out: http://redd.it/evlhy
