This was fixed in Spirit by solving the said problem. You can find the 
solution here:

     <boost/spirit/home/classic/core/non_terminal/impl/static.hpp>
     http://tinyurl.com/byve27

with usage illustrated here, around line 238 (look for 
get_definition_static_data_tag):

     <boost/spirit/home/classic/core/non_terminal/impl/grammar.ipp>
     http://tinyurl.com/cbnuca

Admittedly it can be cumbersome, but it works.

A performance hit has been reported for repeatedly callling call_once, 
that can be solved with double-checked locking. This is not implemented 
in the repository version.

Cheers,
