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

This one is a bit tricky, because the code would
be legal (if memory-leaking) for if a were a pointer.
Also, using a stat variable is supposed to catch this.
Seems like we need a new function for allocating allocatable
arrays, which checks for allocation status and errors out if
the array is already allocated.

There is a problem with the current solution on trunk.
When we do
allocate (a(10))
allocate (a(20),stat=i)
the size information is changed, but the size of the array is not.
