--- Comment #1 from RazvanN <razvan.nitu1305 at gmail.com> ---
Isn't the real bug here the fact that calling ipred passes compilation? As far
as I could tell the lambda template instantion is inside the scope of the S
struct => you cannot call it from fun, since fun may call only const functions
and pred is mutable.
