--- Comment #1 from Daniel Krügler ---
The example looks invalid to me according to [expr.prim.lambda.capture] p7 b
(7.1), because the local variable bj is odr-used in the lambda expression
[](int bk) { a::ac(bk, bj); };
This is so, because the called function template
template void ac(b, const b &);
attempts to bind its second argument by reference.
