rust-overlay: querying packages results in "parentheses not balanced" error

[adelbertc]

This is on macOS Sierra (Darwin), Nix version 1.11.13.

$ nix-env -iA nixpkgs.latest.rustChannels.stable.rust

I'm seeing this same output on (macOS Sierra 10.12.6) after first run of:

nix-env -iA nixpkgs.latest.rustChannels.nightly.rust

$ nix-env --version
nix-env (Nix) 1.11.15

I'm also seeing this on Sierra with Nix 1.11.15. Sean Omlor <notifications@github.com> writes:

Probably due to this: NixOS/nix#1537

It sounds to me that this might be a miss reported OOM error message from libc++.

You can either switch to Nix 1.12 (after updating to the latest version of nixpkgs-mozilla) or try the work-around as suggested in #33 (comment)
