The same issue does appear to exist in that code. The while loop on lines
122-136 reads 4 bytes at a time from iterator->_arg. There is an if statement
(lines 132-135) to prevent going past the end of the buffer, but it only checks
that _arg points within the buffer. If _arg points to the very last byte of the
buffer then the check succeeds, but then four bytes are read, three of which
are past the end of the buffer.
