4 Subject: [PATCH] Bugfix erase() on derived __base_associative
6 When calling erase() on a containers derived from __base_associative
7 (e.g. multimap) and providing a pair of iterators a segfault will
10 Example code to reproduce:
12 typedef std::multimap<int, int> testmap;
14 t.insert(std::pair<int, int>(1, 1));
15 t.insert(std::pair<int, int>(2, 1));
16 t.insert(std::pair<int, int>(3, 1));
17 t.erase(t.begin(), t.end());
