--- Comment #3 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
It also depends on which value is used for 'huge_4', for example no warning
like so:

function foo(bar)
   integer(8)             :: foo
   integer(4), intent(in) :: bar
   ! integer(4), parameter  :: huge_4 = huge(0_4)
   integer(4), parameter  :: huge_4 = 2**30
   foo = (huge_4 - int(bar,kind=8))
end function

there is also no valgrind warning for f951 compiling the testcase.
