Thank you for your fix.
I add one more test multiplying -i.

program pr56015
  implicit none
  complex*16 m(10),p(10)
  m(:) = (0.3d0, 0.4d0)
  m(:) = (0.0d0,-1.0d0) * m(:)
  call bar (m)
  p(:) = (0.1d0, 0.2d0)
  p(:) = (0.0d0, 1.0d0) * p(:)
  call foo (p)
contains
  subroutine bar (m)
    complex*16 m(10)
    if (any (m .ne. ( 0.4d0,-0.3d0))) call abort
  end subroutine
  subroutine foo (p)
    complex*16 p(10)
    if (any (p .ne. (-0.2d0, 0.1d0))) call abort
  end subroutine
end program pr56015
