DatalayerClientSub segmentation fault

[OsamaOAyoub]

Hello,

I have a datalayerClientSub that was running fine and was written based on the sample code provided. However, I had to reinstall my OS and reinstall all libraries including the debian package ctrlx-datalayer and since then there is a specific line causing a segmentation fault.

The segmentation fault happens in the constructor of the datalayerClientSub:

DataLayerClientSub::DataLayerClientSub(const comm::datalayer::DatalayerSystem &datalayerSystem, const std::string &connectionClient)
{
  _datalayerSystem = datalayerSystem;
  _connectionClient = connectionClient;
}

It happens when assigning _datalayerSystem the value of datalayerSystem which is passed when the object is created in main:

auto dataLayerClientSub = new DataLayerClientSub(datalayerSystem, connectionString);

I am not sure what is causing the problem exactly since it was working fine before and I guess assigning the datalayerSystem to the private object _datalayerSystem should be fine.

I also tried to adapt my code to the updated sample, the same problem occurs which is assigning the passed object to the private object.

Thanks, Osama

Only one constructor is called here. If the segment fault comes from this, then the problem is before.

From the description of "DataLayerClientSub" I see that you use a stand 3 years ago. We have revised "DataLayerClientSub" and you can test the example from the SDK if you have problems with it.

I tested it once. With the current example and three years ago, I have no problem.
