You may be encountering the thread-safety bug described in

http://svn.boost.org/trac/boost/ticket/1260

I suspect that the hotfix for 1.34.x that is mentioned in #1260 is

http://boost.sourceforge.net/function-1-34-fix/function_template.hpp

You should try replacing your function_template.hpp with the file above and 
see if it helps.

If you wonder how did I know where to find the hotfix - I googled 
'assign_to_own' :-)
