Another similar error:

./boost/xpressive/detail/core/matcher/regex_byref_matcher.hpp:55:13:
error: cannot convert ‘const boost::intrusive_ptr<const
boost::xpressive::detail::matchable_ex<const char*> >’ to ‘bool’ for
argument ‘1’ to ‘bool boost::xpressive::detail::ensure_(bool,
boost::xpressive::regex_constants::error_type, const char*, const
char*, const char*, long unsigned int)’
