      Bug #38124  (clean-up patch)
      The fix for Bug #38124 introuced a bug. If the value given 
      for a set_var exceeded the length of the temporary buffer,
      we would read behind the end of the buffer.  Using 
      c_ptr_safe(), instead of c_ptr(), ensures that we won't
      read beyond the buffer limit
