#2975 closed Bugs (fixed)

in boost::unordered, incorrect prime_list_template<T>::length

Reported by: Jeffrey Hellrung <jhellrung@…> Owned by: Daniel James
Milestone: Boost 1.39.0 Component: unordered
Version: Boost 1.38.0 Severity: Problem
Keywords: Cc:

Description

In boost/unordered/detail/hash_table.hpp, line 89-90, there is the definition

template<typename T> std::ptrdiff_t const prime_list_template<T>::length = 28;

I believe 28 should be 40 (the number of primes in prime_list_template<T>::value[])...? Otherwise, it seems resizing your hash table past 1.5 million buckets does no good...

Sorry if this has already been reported, but I couldn't find anything when searching the bug tracker.

How embarrasing! Thanks for reporting this.

Duplicates are fine by me, a duplicated bug report is better than no reports. And frankly, if someone had reported this and I hadn't fixed it, I'd deserve much worse.
