Is it legal to reallocate/deallocate the private ALLOCATABLE on the device?
If so, I am not sure this would work after your patch.

Maybe the StackArrays could be extended to deal with scalar allocmem to alloca (assuming you only care about this under optimizations). Although it would likely not be able to deal with this because of the branching logic around the allocation/deallocation.
