Your calling a @system function (constructor) from a safe

Placement new doesn't change the rules around this.
You don't understand: I *WANT* the code *FAIL* to compile because
`S`'s constructor is `@system`. But instead, the `@system`
constructor gets through because I had to use `@trusted` to get
placement new itself to be considered safe. If I have to manually
check constructor safety to get around this then I might as well
just use `emplace`, which would make this a completely worthless
feature.
