I got the following error message when building stylo after upgrading rustc to 1.16.0.

 5:35.36    Compiling geckoservo v0.0.1 (file:///Users/tlin/Projects/gecko-dev/servo/ports/geckolib)

I'll upload a PR to servo/servo.

FWIW, I have the following in my MOZCONFIG.

ac_add_options --enable-debug
ac_add_options --disable-optimize

Pushed a try to test building without --disable-optimize

Probably a recent regression. Stylo builds fine with Rust 1.16.0 before mozilla-central changeset e3e83e6bf409 or https://github.com/servo/servo/commit/1bacd0eb1582
