USM offload issue

Following the example listed in

My variation of the test program errors out with

"PluginInterface" error: Failure to run target region 0x000002067f104068 in device 0: "unknown or internal error" Error in launch Kernel __omp_offloading_b46132e0_9a052b74_MAIN___l51: -1

Using Arc Pro B50

I reduce the program to that as was illustrated (but added one print statement at the end).

Still fails

!  GPUtest3.f90 
program GPUtest3
    use omp_lib
    implicit none
    integer, parameter :: N=16
    integer :: i, dev
    integer, allocatable :: x(:)
    dev = omp_get_default_device()
    !$omp allocate allocator(omp_target_shared_mem_alloc)
    allocate(x(N))
    
    do i=1,N
            x(i) = i
    end do
    
    !$omp target has_device_addr(x)
    !$omp teams distribute parallel do
    do i=1,N
        x(i) = x(i) * 2
    end do
    !$omp end target
    print *, x
    deallocate(x)
end program GPUtest3
