Comment:

 The stack trace indicates that the issue resides in either spirit or
 shared_ptr libraries which are used for loading xml files.  There is
 information related to using BOOST_USE_PTHREADS in the shared_ptr library.
 Other than that, I don't know much about it.  Note that the serialization
 library (as far as I know) is thread safe without the need for doing any
 locking.

 FYI, here is the code from xml_grammar.cpp


 {{{
 ypedef basic_xml_grammar<char> xml_grammar;

 /////////1/////////2/////////3/////////4/////////5/////////6/////////7/////////8
 // specific definitions for char based XML

 template<>
 void xml_grammar::init_chset(){
     Char = chset_t("\x9\xA\xD\x20-\x7f\x80\x81-\xFF");
     Letter = chset_t("\x41-\x5A\x61-\x7A\xC0-\xD6\xD8-\xF6\xF8-\xFF");
     Digit = chset_t("0-9");
     Extender = chset_t('\xB7');
     Sch = chset_t("\x20\x9\xD\xA");
     NameChar = Letter | Digit | chset_p("._:-") | Extender ;
 }

 }}}

 This is the last the serialization library sees of it before it tanks.

 I've tried to pass this on to Joel Guzman the inventor of spirit library
 but I've been unable to find his name here.  So for now, I'm forwarding
 this to no_maintainer.  Sorry I couldn't be of more help.
