Issue #12956 has been updated by Nobuyoshi Nakada.

Backport changed from 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN to 2.1: REQUIRED, 2.2: REQUIRED, 2.3: REQUIRED

Thank you for heading up.

I found that it works on OS X El Capitan too.
It was OS X Yosemite when I added that line (May 2015), and probably `dlclose` was fixed in El Capitan.

Bug #12956: require a native library that yields the error 'incompatiable library version' shuts down the interpreter fatally

* ruby -v: ruby 2.3.2p217 (2016-11-15 revision 56796) [x86_64-darwin16]
* Backport: 2.1: REQUIRED, 2.2: REQUIRED, 2.3: REQUIRED
----------------------------------------
I would like to rescue from this in ruby-code.
Looking at the source in dln.c around line 1334 shows, that there is a special APPLE define with a comment that suggests, that properly cleaning up with dlclose crashes.
Disabling the special handling on my machine running OSX Sierra 10.12.1 did not show the crashing behavior, but instead I was able to rescue from the LoadError.
To reproduce I attached my native extension. To reproduce this just run irb -I. and require 'dotstar'
