[Bug fortran/44604] New: Wrong run-time checks with VALUE dummies and pointer/allocatable actuals

[burnus at gcc dot gnu dot org]

Reported by Michael Briggs at
http://gcc.gnu.org/ml/fortran/2010-06/msg00205.html

Checking fails for a zero-initialized pointers/allocatable scalar
variable/array element passed to a dummy argument with VALUE attribute.

For the following program, it fails for -fcheck=all:

program TestSmall
  implicit none
 integer, allocatable :: ptrVar
  allocate ( ptrVar )
  ptrVar = 0  ! if changed to 1, the problem goes away
  call test(ptrVar)
contains
  subroutine test(n)
     integer, VALUE :: n
  end subroutine test
end program TestSmall
