'Invalid codename string' panick

[PuKoren]

Hello all.

I'm trying to use the crate and I have some runtime error:

thread 'main' panicked at 'Invalid codename string', src/libcore/option.rs:699
note: Run with `RUST_BACKTRACE=1` for a backtrace.
fatal runtime error: failed to initiate panic, error 5
error: An unknown error occurred

I'm using the sample code from the Readme:

  match cpuid::identify() {
    Ok(info) => {
        println!("Benchmarking {} CPU, model: {}", info.vendor, info.codename);
    },
    Err(err) => println!("cpuid error: {}", err),
  };

Using OSX, compiled and installed libcpuid (otherwise the crate refused to compile), seems be ok on this side.

Will try again later on a GNU comp to see if related or not
