! This program violates requirements of 6.3.1 of the F95 standard.

! An allocate-object, or a subobject of an allocate-object, shall not appear
! in a bound in the same ALLOCATE statement. The stat-variable shall not appear
! in a bound in the same ALLOCATE statement.

! The stat-variable shall not be allocated within the ALLOCATE statement in which
! it appears; nor shall it depend on the value, bounds, allocation status, or
! association status of any allocate-object or subobject of an allocate-object
! allocated in the same statement.

  integer, allocatable :: ALLOCS(:)

  allocate (PTR, stat=PTR) ! { dg-error "allocated in the same statement" }
