   Status:  new                   |  Milestone:  To Be Determined
Component:  None                  |    Version:  Boost 1.54.0
 Severity:  Problem               |   Keywords:
----------------------------------+------------------------------
 If boost::format_date_parser::parse_date is given a format_str such as "%"
 then the loop in date_time\format_date_parser.hpp:

 {{{#!c++

     while (itr != format_str.end() && (sitr != stream_end)) {
       if (*itr == '%') {
         itr++;
         if (*itr != '%') { // <<< ERROR here
           switch(*itr) {
           case 'a':
 }}}

 tries to dereference the one-past-the-end character on the line marked.

 With a debugging iterator (eg MSVC) this causes runtime failure.
