It looks like this is an issue with a bundled dependency, hiredis. Here's a GitHub issue that might be related: ​https://github.com/antirez/hiredis/issues/53

The same error happens with Redis 4.2.1.

Shoot. I upgraded the Redis port the night before upgrading to Xcode 4.2. Should be fixed now in r85937. Let me know if you still have problems.
