java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

OS X El Capitan 10.11.5

Graphics Intel Iris Pro 1536 MB


A DESCRIPTION OF THE PROBLEM :
Android Studio 2.x crashes consistently after a few minutes of use. simply navigating around a project, opening/closing files, is sufficient to produce a crash. i have not yet been able to find a deterministic way to cause a crash. it seems to happen randomly, but always within a few minutes (< 5min) of light usage.

Android Studio 1.x does not suffer this problem.
