Hi, While developing skip_xml_iarchive, I noticed to bugs in basic_xml_iarchive::load_end(). 1. The sense of the check of the flags against no_xml_tag_checking is reversed. By default, checking of xml tag names is not done, contrary to the documentation. If no_xml_tag_checking is passed in as a flag, tag checking is enabled. 2. If tag checking is enabled, and a tag name is encountered that is longer than the name passed in, the name string is accessed past the end of the array. In the expression "name[this->This()->gimpl->rv.object_name.size()]", the index is the size of the encountered name, and could be arbitrarily large. The relevant portion of basic_xml_iarchive::load_end() is included here: if(0 != (this->get_flags() & no_xml_tag_checking)){ if(0 != name[this->This()->gimpl->rv.object_name.size()] || ! std::equal( this->This()->gimpl->rv.object_name.begin(), this->This()->gimpl->rv.object_name.end(), name ) My recommended fix for (1) would be to change no_xml_tag_checking to check_xml_tags, and to change the documentation to reflect this. While the more obvious solution would be to simply fix the comparison, this would introduce a silent behavioral change. My recommended fix will fail to compile for those that have specified no_xml_tag_checking, thus alerting them to the change. My recommended fix for (2) is to replace the excerpted code with: if(0 != (this->get_flags() & check_xml_tags) && rv.object_name != name) The Boost FAQ recommends posting bug reports to the mailing list. Let me know if you would like for me to submit this to the bug repository. -- Todd Greer <tgreer <at> affinegy dot com> Senior Software Developer, Affinegy LLC
