[Bug fortran/25031] New: Allocatable array can be reallocated.

["iguchi at coral dot t dot u-tokyo dot ac dot jp" <gcc-bugzilla at gcc dot gnu dot org>]

In the following program, the run-time error should occur.
at the second allocation.

But I can successfully executed the program.
And at the second allocation, memory leak is also occur.

I think this is wrong behavior.

program alloc_test
  implicit none
  integer, allocatable :: a(:)

  allocate(a(4))
  allocate(a(4))
end program
