Expand(), memory keeps increasing #2148

When I run the following code, the memory usage keeps increasing iteration by iteration.

while True:
  a = Variable(torch.FloatTensor(32,16).cuda())  
  r = Variable(torch.FloatTensor(1).cuda())
  c = r.expand(a.size())

If I use r.exapnd([32, 16]), memory usage does not increase.
Did I use expand() incorrectly? Does anyone have the same issue?

This is not happening on master or v0.2.0

(Neither CUDA memory or CPU memory is increasing)
