Not even on nightly? I know that we don't tend to mess with things unless they're behind unstable feature flags (which you presumably aren't using), but I'd be very pleasantly surprised if we managed to make nightly stable enough that you never happened to run into any compiler bugs. :)

So I have 20,292 lines of Rust with 85%ish code coverage in my project (by current count), and I can't recall a failure in nightly since I enabled it in Travis. Mind you, that only gets run when a commit happens, so it's entirely possible it could have failed and I've just been lucky. It looks like from git log, I committed the change to Travis to start nightly builds on

So, take that for what it's worth :)
