Your problem is not caused by "the structure of boost qi" and is also
unrelated to your upgrade to g++ version 6.2.0 since your code fails to
compile with the exact same error: "error_invalid_expression". The error
message points to this section of the code
https://github.com/boostorg/spirit/blob/develop/include/boost/spirit/home/qi/nonterminal/rule.hpp#L177
that explains the problem further. Sadly the error does not point where in
your code is the problem, but I can tell you that it is located in your
"symbol_def_expr" rule (that reduces the lines you need to inspect to "just"
32).
