  • Allocating 16 bytes more for the MEMALIGN_HACK is enough. There's no
    need for 1 more extra byte.
  • Checking whether the to be allocated size is larger than INT_MAX,
    doesn't assure that size+16 bytes for the MEMALIGN_HACK isn't larger
    than INT_MAX.
  • malloc might return NULL. Checking for it before using that pointer...

The AAC frame header uses 13 bits for the frame size, so the buffer should
have room for such a frame. A frame that large seems unlikely in a valid
file, but leaving room for it spares us the need to check it elsewhere.
Moving the buffer to the end of the struct made debugging this easier....
