Uploaded reproducible code to Gist: https://gist.github.com/rhenium/e3a179b0cac87606c183

This runs on Ruby 2.2.4 and patched trunk but segfaults on trunk.

* ruby -v: ruby 2.3.0dev (2015-12-20 trunk 53215) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
When the control frame stack contains an ifunc-frame, calling rb_profile_frames() causes a segmentation fault.

I've attached a patch that changes it to ignore ifunc frames as it did previously.
