You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

@little-arhat have you tried with 1.4? does it still ICE?

[little-arhat]

I have installed multirust and then nightly via it.

1.4 has been just successfully installed!

[steveklabnik]

Okay. I'm going to give this a close then, as it must have been some sort of transient thing. Thanks for reporting!
