Section 8.2.2 says:

On mid-page 34, there is the code:

/*
 * add "length" to the length
 */
static uint32_t addTemp;
#define SHA224_256AddLength(context, length)               \
  (addTemp = (context)->Length_Low, (context)->Corrupted = \
    (((context)->Length_Low += (length)) < addTemp) &&     \
    (++(context)->Length_High == 0) ? 1 : 0)

It should say (modifying the last line):

/*
 * add "length" to the length
 */
static uint32_t addTemp;
#define SHA224_256AddLength(context, length)               \
  (addTemp = (context)->Length_Low, (context)->Corrupted = \
    (((context)->Length_Low += (length)) < addTemp) &&     \
    (++(context)->Length_High == 0) ? shaInputTooLong : shaSuccess )

Rationale:  Same as for item (7) above.
