> pointer aliasing Unfortunately, due to LLVM bugs, the Rust developers had to disable that optimization, more than once. I don't know whether the "1.13.0-nightly" he used has that optimization enabled or disabled. (See https://github.com/rust-lang/rust/issues/31681 https://github.com/rust-lang/rust/issues/31681 and https://github.com/rust-lang/rust/issues/54878 https://github.com/rust-lang/rust/issues/54878 for the relevant Rust issues.)
