Summary:
Our app is seeing sporadic crashes on launch when using dynamic libraries. This is only when running the app store release on device. 

The problem is described in detail here: https://github.com/artsy/eigen/issues/1246

Steps to Reproduce:
There is no simple way to reproduce. It appears to happen on devices that are memory-constrained, as freeing up RAM on the device causes the app to no longer crash.

Expected Results:
The app doesn't crash on launch

Actual Results:
The app crashes and produces a log similar to the one attached to the radar:

Dyld Error Message:

  Dyld Version: 370.6

Regression:
This only seems to occur on iOS 9.1 and greater.

Notes:
For some reason the app will successfully launch when opened via a push notification (?!).
