Summary: use of deleted memory in __gnu_cxx::hashtable::erase Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: libstdc++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: dtar...@redhat.com Created attachment 24289 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24289 reproducer How to reproduce: 1. get the attached reproducer 2. g++ -Wall -g -O0 hashtable.cc -o hashtable 3. valgrind ./hashtable Note: I think this cannot be triggered through normal use of std::hash_map or std::hash_set, because it requires that the bucket contains two nodes with equal key.
