----------------------------------------
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'
