Hi team,
I'm working on SDK 08_02_00_05(Linux+RTOS).
When testing a application, I'm facing the below Segmentation fault.
In app_run_graph_for_one_frame_pipeline function, after completing execution of if(obj->pipeline < 0), it is directly reaching end of app_run_graph_for_one_frame_pipeline, instead of executing else if(obj->pipeline >= 0), which causing segmentation fault.
What could be the reason for this behaviour? how to avoid it.
