_scheduler.so segfault when Mesos is built with Xcode 8.3.2

Testing on macOS Sierra 10.12.5.

Note: This bug does not occur if you build Mesos with Xcode 8.2.1 instead of with Xcode 8.3.2.

The bug affects affects Mesos 1.2.0, and still affects 1.3.0-rc3.

The crash occurs at run time if you run `python -c "import mesos.native"`

It appears to be a segfault in _scheduler.so.

In particular, this is Mesos built with Homebrew (https://github.com/Homebrew/homebrew-core/blob/master/Formula/mesos.rb)
