Hello All,
I have written a native addon [Using NAN] for my cpp [pub-sub] library.
- Subscriber that is receving the events from the publisher.
- Calling the application callback.
So, my native addon is providing wrapper APIs for cpp library.
- Js application will create subscriber object and will subscribe for event. Internally I am creating c++ subscriber, subscribe to it and will register addon callback to cpp layer.
- I am using libuv for getting the asyn callback from c++ layer to addon layer, and then I am calling NAN callback for calling js callback.
For callback implementation in addon, I followed: #1171
Issue:
After receving some events on subscriber side, subscriber sample is crashing [Segmentation fault].
Crash logs:

Observation:
There is a strange observation on my subscriber sample:
- If, I am creating my subscriber object in sample application like this:
subscriber = new subscriber(ip, port);
Result: It is working fine.
- If, I am creating the subscriber object like this
var subscriber = new subscriber(ip, port);
Result: It is crashing after receiving some events.
Environment details:
- Node.js Version: v8.11.1
- OS: Linux [Ubuntu : 14.04]
I am struggling with this issue since quite long. Any help will be appreciated.
Thanks in advance.
