   2 ! PR 25031 - We didn't cause an error when allocating an already
   3 !            allocated array.

  11   ! This should set the stat code and change the size.
  12   allocate(a(3),stat=i)
  13   if (i == 0) call abort
  14   if (.not. allocated(a)) call abort
  15   if (size(a) /= 3) call abort
  16   ! It's OK to allocate pointers twice (even though this causes
  17   ! a memory leak)
