invalid memory size

Running this code:


```python
x = torch.LongTensor(3, 4).random_(10)
torch.LongTensor(x.numpy()[::-1])
```

returns the following error:
```RuntimeError: $ Torch: invalid memory size -- maybe an overflow? at /home/guismay/pytorch-master/torch/lib/TH/THGeneral.c:257```

So I have to run `torch.LongTensor(x.numpy()[::-1].copy())`instead.
