On most platforms, the `environ` symbol is accessible everywhere. In a dylib on OSX, it's not easily accessible, you need to find it with _NSGetEnviron. The code was caching the *value* of environ. But a setenv() can change the value, leaving garbage at the old value. Fix: don't cache the value of environ, just read it every time.
