PR libstdc++/54296
* include/bits/hashtable.h (_M_erase(size_type, __node_base*,
__node_type*)): New.
(erase(const_iterator)): Use latter.
(_M_erase(std::true_type, const key_type&)): New, likewise.
(_M_erase(std::false_type, const key_type&)): New. Find all nodes
matching the key before deallocating them so that the key doesn't
get invalidated.
(erase(const key_type&)): Use the new member functions.
* testsuite/23_containers/unordered_map/erase/54296.cc: New.
* testsuite/23_containers/unordered_multimap/erase/54296.cc: New.
