Based on http://lists.boost.org/MailArchives/boost/msg75057.php and the fact I don't have OS X around I concluded there was nothing I could do about it. It would seen easy to address untill there's a new version of the compiler by tweaking one of the build Jamfiles to supress one or more of the optimizations for this platform. This was the thrust of my suggestion in http://lists.boost.org/MailArchives/boost/msg75058.php . I don't think this would take very long to do - but it does require understanding of how to tweak the Jamffile for the library build which could also be an obstacle. Another quick and dirty option is just to comment out the xml_grammar from the list of library source in the Jamfile. This would build the library without the xml capability.

What is the state of the release build hang on xml_grammar.cpp on OS X? Has anyone endevoured to block out the offending optiminzation?
This is were I saw the message discussed last.
