Bug #: 57065
Summary: incorrect default allocator template for debug and
profile unordered_map
Classification: Unclassified
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: libstdc++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: theonetruekenny@yahoo.com
In libstdc++-v3/include/debug/unordered_map and
libstdc++-v3/include/profile/unorderd_map, the unordered_map template is
defined as:
template<typename _Key, typename _Tp,
typename _Hash = std::hash<_Key>,
typename _Pred = std::equal_to<_Key>,
typename _Alloc = std::allocator<_Key> >
class unordered_map
however, the correct definition (as reflected in bits/unordered_map.h) is:
* @param Pred Predicate function object type, defaults to
equal_to<Value>.
* @param Alloc Allocator type, defaults to allocator<Key>.
*
* The resulting value type of the container is std::pair<const Key, Tp>.
*/
template<class _Key, class _Tp,
class _Hash = hash<_Key>,
class _Pred = std::equal_to<_Key>,
class _Alloc = std::allocator<std::pair<const _Key, _Tp> > >
class unordered_map
note that the comment is wrong, but the code is correct.
See also: http://www.cplusplus.com/reference/unordered_map/unordered_map/ which
matches the definition in bits/unordered_map.h
As far as I can tell, this error has existed since gcc 4.3.

Note that the www.cplusplus.com documentation has unordered_multiset wrong ;)
