Date time parsing with a particular format string dereferences an end iterator

Description

Using the "%s" format flag with an input string that does not end with fractional seconds leads to dereferencing of an "end" iterator, causing memory corruption.

Sample code: 

std::string fmt = "%Y-%m-%d %H:%M:%s";
std::stringstream ss;
ss.imbue(std::locale(ss.getloc(), new boost::posix_time::time_input_facet(fmt)));
ss << "2010-05-10 10:03:05";
boost::posix_time::ptime pt;
ss >> pt;
