Segmentation Fault arises when initializing a publisher in a constructor

[CuiiGen]

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

We define a class, and it has only one private member variable mypub, an instance of the Class MsgPublisher.
We then call its initialization method mypub.init() in the constructor of MsgPublisher.

Current behavior

Segmentation Fault arises when initializing that publisher.

Steps to reproduce

Here is an example to reproduce this issue.
TestDDS - 20231114.zip

mkdir build
cd build
cmake ..
run ./TestDDS

Here is the information from the call stack when running the program in debug mode.
The last three lines indicate where the error occurs in my code.

Hi @CuiiGen,

Thanks for the report and code sample. I could reproduce the problem. It seems to me that the problem has to do with the static variable initialization which may be unpredictable in early initialization and different across platforms. I suggest making the InputRecvData_arg, OutputSendData_arg and TestDDS_Obj non static as well as creating them within main, passing a capture of TestDDS_Obj by reference to the periodic event handler.
Let us know if that helps.
