Bug #6576: shared library references _environ macosx Lion
https://bugs.ruby-lang.org/issues/6576#change-27177

Author: djk (Daniel Kopetzky)
Status: Feedback
Priority: Normal
Assignee: kosaki (Motohiro KOSAKI)
Category: core
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-06-10) [x86_64-darwin11.4.0] 


The code in missing/setproctitle.c references the global variable environ.
The environ global variable isn't allowed in mac dylib shared libraries.
Code trying to use ruby-2 as a shared library will fail.

% nm libruby.dylib|grep _environ
                 U _environ

The code in hash.c has #ifdef __APPLE__ sections that appear to access
the environment using Apple's suggested _NSGetEnviron() routine.
