I am running a custom c++ library with python bindings. A .so (shared object) file is being dynamically linked to the python program. The python file is importing the custom c++ library . When I run the python file using python3 filename.py I receive the error : Segmentation fault(core dumped) I tried debugging this error using gdb for python. I need help in understanding what the above links are pointing to and how this issue can be resolved.
