When I link this layer  with another convolution layer and forward, the computation will be \"stuck\". However, if I link the layer with other types of layers such as softmax or directly set it as output, the result is correct. This suspicious bug appears when the batch_dot executes more than 3 times.\r\n\r\nHere is the code \r\n[mxnet_issue_multiple_batch_dot.txt](https://github.com/dmlc/mxnet/files/405017/mxnet_issue_multiple_batch_dot.txt)\r\nthat can reproduce the error.
