! { dg-do run }

! Scalar coarray
!
! Run-time test for IMAGE_INDEX with cobounds only known at
! the compile time, suitable for any number of NUM_IMAGES()
! For compile-time cobounds, the -fcoarray=lib version still
! needs to run-time evalulation if image_index returns > 1
! as image_index is 0 if the index would exceed num_images().
!
! Please set num_images() to >= 13, if possible.
