karroffel 30822e8ab7 fixed crash with StringBuilder
When using a newly created StringBuilder then the as_string() method
will crash when trying to free an allocated 0-sized chunk of memory.

When 0 bytes get allocated with memnew_arr then a NULL pointer gets
returned. When trying to free that pointer the programm will crash.
