The code above passes (i + TUPLE_INDEX_BASE) to diag_set. Please fix
this place to conform.

Extra space before "The region is used ...". Makes the comment difficult
to read.

assert(parent != NULL);

would be useful here to show the reader that top-level fields have
already been created someplace else.

Better 'return parent;' - we don't need to call tuple_field_delete() in
this case.

Call them simply 'stack' and 'frames'.

I don't like that frame->curr index is in fact 1-based. Let's initialize
frame->curr with -1 (or UINT32_MAX) in mp_stack_push() so that the first
mp_stack_advance() called after mp_stack_push() would set it to 0.

Also, what about changing the API slightly?

	mp_stack_advance() -> item index (>= 0) on success
			      -1 if all items have been processed.

Then we wouldn't really need to access mp_frame to get 'curr' so we
could replace mp_stack_top() with mp_stack_type() => MP_MAP/MP_ARRAY.
Not sure if it's a really good idea though. The code would look more
concise, but need to check.

The code would look better IMO if you rewrote it without double-if
(first check frame->type to initialize token.type, then check
token->type to initialize token.key):

		switch (mp_stack_top(&stack)->type) {
		case MP_MAP:
			token.type = JSON_TOKEN_STR;
			token.str = ...
			break;
		case MP_ARRAY:
			token.type = JSON_TOKEN_NUM;
			token.num = ...
		default:
			unreachable();
		}

The semicolon (;) isn't needed.

This isn't how this assertion should be fixed - instead we should check
tuple_field_count for keys only (i.e. SELECT statements):

	/* All key parts must be set for a point lookup. */
	assert(vy_stmt_type(key) != IPROTO_SELECT ||
	       tuple_field_count(key) >= lsm->cmp_def->part_count);
