--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The difference is in the case of the lambda it is not an indirect function call
so the test call/lambda is inlined early into std::ranges::count_if and that
will be inlined into count2/test2 to get the non loop version.
In the case of std::bind_front, there is an indirect function call.
std::ranges::count_if is not early inlined into count1 and the indirect
function call is NOT turned into a direct function call until after inlining so
we miss out that Foo::find not being inlined and then the loop stays around.
