mem::transmute: Compile error on 32bit linux

Was wondering why it passed on travis but that uses rustc 1.6.0

32 bit linux. Looks like its because pointer size differences.

Not sure if I am getting it correctly: You are trying to compile on a 32bit Linux with Rust 1.7?

I first thought its an issue with rust 1.7 but its obvious its a 32 bit pointer (32 bit linux) being transmuted to a u64.
