What happens if you uninstall the rustfmt-nightly and use the component instead?

(TryFrom is being stabilized fairly soon, it got caught up in some silly stuff but is basically good to go)

So on the mac, something's going on and even with LIBCLANG_PATH set I'm still getting a segfault in some clang stuff. On the BSD box, rustfmt-nightly allows everything to work. Using `cargo install --force rustfmt` will provoke bindgen into reporting an internal error:

Custom { kind: Other, error: StringError("Internal rustfmt error") }

I get the same results if I call the bindgen executable or have build.rs call the bindgen API. I've stuck with having build.rs call the bindgen executable because if I use the bindgen API, compilation is SLOW.

Not cargo install, the

    rustup component add rustfmt-preview

Results:

  $ cargo uninstall rustfmt && rustup component add rustfmt-preview

  #include <r_bin.h>

Okay. Let’s get that bug re-opened!
