Interesting. You're not actually quoting the full sentence:
If the constant-expression is present, it shall be a converted
constant expression of type std::size_t and its value shall be
greater than zero.
This suggests that:
__u64 ptr[]
is actually valid since:
D1 [ constant-expressionopt ] attribute-specifier-seqopt
suggests that the part between the brackets is optional.
