The standard does not require the constructor `strstreambuf(streamsize alsize_arg = 0)` leave the stream array unallocated when called with parameter `alsize_arg > 0`. Conformant implementations of this constructor may allocate minimal `alsize_arg` number of bytes forcing `str()` method to return non-null pointer.
