--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Not a bug, the standard is clear about this:

[Note 2 : Unless otherwise specified, algorithms that take function objects=
 as
arguments can copy those function objects freely. If object identity is
important, a wrapper class that points to a non-copied implementation object
such as reference_wrapper<T> (22.10.6), or some equivalent solution, can be
used. =E2=80=94 end note]=
