| ! PR 50564 - this used to ICE with front end optimization. |
| ! Original test case by Andrew Benson. |
| program test |
| implicit none |
| double precision, dimension(2) :: timeSteps, control |
| integer :: iTime |
| double precision :: ratio |
| double precision :: a |

| ratio = 0.7d0 |
| control(1) = ratio**(dble(1)-0.5d0)-ratio**(dble(1)-1.5d0) |
| control(2) = ratio**(dble(2)-0.5d0)-ratio**(dble(2)-1.5d0) |

| end forall |

| ! Make sure we still do the front-end optimization after a forall |
| a = cos(ratio)*cos(ratio) + sin(ratio)*sin(ratio) |
| if (abs(a-1.d0) > 1d-10) STOP 2 |
