Related issue but without an ICE:

   contains
      integer function f1()
        !f2 = 1   ! gives an error as expected
        j = f2    ! <<<< accepted; cast of function addr to integer(kind=4)
        f1 = 1    ! ↑ ifort: 'already been used as an external function name'
      end function
      integer function f2()
        f2=1
      end function
   end
