# intrusive::unordered_set::suggested_lower_bucket_count

### Description

The above static method crashes or doesn't return the correct value.

Code in boost 1.41 is:

static size_type suggested_lower_bucket_count(size_type n)

{

const std::size_t *primes = &detail::prime_list_holder<0>::prime_list[0];

const std::size_t *primes_end = primes + detail::prime_list_holder<0>::prime_list_size;

size_type const* bound = std::upper_bound(primes, primes_end, n);

if(bound != primes_end)

bound--;

return size_type(*bound);

}

I think it should be:

static size_type suggested_lower_bucket_count(size_type n)

{

const std::size_t *primes = &detail::prime_list_holder<0>::prime_list[0];

const std::size_t *primes_end = primes + detail::prime_list_holder<0>::prime_list_size;

size_type const* bound = std::upper_bound(primes, primes_end, n);

if(bound != primes)

bound--;

return size_type(*bound);

}

Thank you,

Etienne
