Using minicaffe net as a class member

[ligongzheng]

Hello,
I have a class like:
class A {
private:
caffe::Net* net_;
}

The constructor like:
A:A(){
net_ = new caffe::Net("**.prototxt");
}
A weird question was occurred:
When I use the class A like:
A = new A();
Everything is OK.

But when I use the class A like:
A a;
A crash happened ! After I run forward of net, I get a nan result.

What does a crash happened mean? segment fault? Did you initialize the network parameters?
