zhanghang1989 opened a new issue #10976: MNIST LeNet forward fails on master branch
URL: https://github.com/apache/incubator-mxnet/issues/10976
 
 
   MNIST LeNet forward fails on master branch. @eric-haibin-lin mentioned that it may be related to this PR https://github.com/apache/incubator-mxnet/pull/10911
   ```python
   import mxnet as mx
   from mxnet.gluon import nn, Block
   net = nn.HybridSequential()
   with net.name_scope():
           net.add(nn.Conv2D(in_channels=1, channels=20, kernel_size=5))
           net.add(nn.Activation('relu'))
           net.add(nn.MaxPool2D(pool_size=2, strides=2))
           net.add(nn.Conv2D(in_channels=20, channels=50, kernel_size=5))
           net.add(nn.Activation('relu'))
           net.add(nn.MaxPool2D(pool_size=2, strides=2))
           # The Flatten layer collapses all axis, except the first one, into one axis.
           net.add(nn.Flatten())
           net.add(nn.Dense(512,in_units=800))
           net.add(nn.Activation('relu'))
           net.add(nn.Dense(10, in_units=512))
   net.collect_params().initialize()
   x = mx.random.uniform(shape=(8, 1, 28, 28))
   net(x)
   ```
   Got this error
   ```bash
   Segmentation fault (core dumped)
