--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> 2010-11-11 09:30:40 UTC --- (In reply to comment #1) > I forgot to mention one thing.

This invalidates out. > std::map<PublicKey, std::set<PublicKey> >::const_iterator giter = graph.find( > *out ); And now you dereference an invalid iterator. This looks clearly broken to me, but I have only looked briefly. Please follow GCC's bug reporting guidelines and provide a self-contained testcase without other libraries - I'm not going to download and install them. Provide preprocessed source if you really can't remove them. Please also try compiling with -D_GLIBCXX_DEBUG, or changing the type of toDo to __gnu_debug::set<PublicKey>, after including <debug/set>, which might tell you the problem.
