Section 8.2.3 says:

The sample code presents almost all formal function arguments of type
array with predefined (constant) length with this explicit length.
Contrary to that, the function definitions for SHA384_512Reset do not
supply the expected size of the formal argument 'H0'.
This inconsistency should be corrected -- as in items (18) and (28)
above.

Near the top of page 65, RFC 4634 says:

#ifdef USE_32BIT_ONLY
static int SHA384_512Reset(SHA512Context *context, uint32_t H0[])
#else /* !USE_32BIT_ONLY */
static int SHA384_512Reset(SHA512Context *context, uint64_t H0[])
#endif /* USE_32BIT_ONLY */

For consistency and clarity, it should say:

#ifdef USE_32BIT_ONLY
static int SHA384_512Reset(SHA512Context *context,
                           uint32_t H0[SHA512HashSize/4]);
#else /* !USE_32BIT_ONLY */
static int SHA384_512Reset(SHA512Context *context,
                           uint64_t H0[SHA512HashSize/8]);
#endif /* USE_32BIT_ONLY */
