EDIT: There was a request here for clarification on why the patch worked, since unsetenv was being called on the same vars in the unpatched code. Thanks for the explanation, cperciva.
The problem is that the unsetenv function was POSIXified to make it return int when it used to return void; and then it started returning -1 when the environment was corrupt.
