Yes, it's a known Rust bug.  We've hit it before, see thread
"Re: 01/03: llvm: Build with RTTI by default".

Also see https://github.com/rust-lang/rust/issues/43402 (the fix is
supposed to be in 1.22.1, though).

It should work when you try again.

If someone has it fail reproducibly (or at least often enough that you can
reproduce it once), please try to invoke the command above, but without the
"grep".  It would be interesting to know what it said.
