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 prototypes for SHA384_512Reset do not
supply the expected size of the formal argument 'H0'.
This inconsistency should be corrected -- as in item (18) above.

There are two instances of the issue (see item (xx) below for
another two similar instances, with the function declarations):

(28a)
Within the function prototype definition part of the
  '#ifdef USE_32BIT_ONLY'
branch of the sample code, near the bottom of page 50, the RFC says:

static int SHA384_512Reset(SHA512Context *context, uint32_t H0[]);

For consistency and clarity, it should say:

static int SHA384_512Reset(SHA512Context *context,
                           uint32_t H0[SHA512HashSize/4]);

(28b)
Within the function prototype definition part of the
  '#else /* !USE_32BIT_ONLY */'
branch of the sample code, near the bottom of page 51, the RFC says:

static int SHA384_512Reset(SHA512Context *context, uint64_t H0[]);

For consistency and clarity, it should say:

static int SHA384_512Reset(SHA512Context *context,
                           uint64_t H0[SHA512HashSize/8]);
