Comment (by juanpablo.canepa@…):

 I managed to reduce the problem to a very simple grammar, that I've
 attached to this ticket. The problem seems to be that boost.spirit, for
 some reason, assumes there is a nested field called "types" in
 boost::optional, that was removed after 1.61, that was defined:

 {{{
 typedef BOOST_DEDUCED_TYPENAME
 mpl::if_<is_reference_predicate,types_when_ref,types_when_not_ref>::type
 types ;
 }}}

 This is blocking a release of one of our tools, so if there was any
 workaround that we can patch locally, I'll take it for the time being.
