Simplest possible code:
#include "mongo/client/dbclient.h" // for the driver

int main()

{ mongo::client::initialize(); return 0; }

compilled with:
g++ mongo_crash.cc -std=c++11 -pthread -lmongoclient -lboost_thread-mt -lboost_system -lboost_regex -o mongo_crash

causes segfault in mongo::client::initialize(). gdb says its somewhere in the ~Options(), but I don't understand what's going on. Without -std=c++11 everything works.

The driver sources have been cloned out and built few days ago.
