Using invalid iterator

Undefined behavior may result; the program may crash or subtly misbehave. An invalid or past-the-end iterator is being used
/test/simulator/timestamp/src/session_simulator.cpp:354: INVALIDATE_ITERATOR 138822 Calling "find" with element ""get"" returns the end iterator.
/test/simulator/timestamp/src/session_simulator.cpp:354: INVALIDATE_ITERATOR 138822 Assigning: "pos" = "config_map.find(std::map<std::_cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::less<std::cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<std::cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const, std::_cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >::key_type const("get", std::allocator<char>()))".
