Comment (by eric_niebler):

 In parser_traits.hpp:

 {{{
             case BOOST_XPR_CHAR_(char_type, 'P'):
                 this->eat_ws_(++begin, end);
                 BOOST_XPR_ENSURE_(begin != end, error_paren, "incomplete
 extension");
                 switch(*begin)
                 {
                 case BOOST_XPR_CHAR_(char_type, '<'):
                     this->eat_ws_(++begin, end);
                     switch (*begin)
                     ^^^^^^^^^^^^^^^
 Whoops! Doesn't check that begin != end before dereferencing begin!
 }}}
