Actually, The code does:
environ = cleanenv;
free(cleanenv);
Is this an issue where I should be doing memcpy(&environ, &cleanenv)?
The current code works fine on FreeBSD.

environ is a pointer. cleanenv is a pointer. You assign environ to be a
pointer to what is stored in cleanenv, then you deallocate cleanenv. That
means the memory is no longer valid; on many systems the data will still
be there, but that's a fluke. Perhaps you just aren't awake yet (I know
the feeling...) or I'm missing something...
