t.cudafe1.stub.c:8: error: invalid cast from type ‘const expr<boost::proto::exprns_::basic_expr<boost::proto::tag::address_of,
Proto overloads the addressof operator (unary &) to build a tree node. It seems somewhere someone is trying to take the address of proto expression and getting a new object instead. (Whoever it is should be using boost::addressof, or the equivalent. That's busted.) Proto address_of nodes are implicitly convertible to an expression pointer to generally avoid this sort of problem, but it looks like the compiler is trying to cast to "char*" instead. (That's also busted.) The workaround would be to disable Proto's operator overload. struct domain : proto::domain< proto::pod_generator<expr> , proto::not_<proto::address_of<proto::_> >
