A Segmentation Fault in multi-threaded programming implies an error caused by accessing memory that “does not belong to you.” It’s a common issue when dealing with threads and shared data. This can lead to unpredictable behavior, as the thread causing the fault may be terminated or other threads may continue executing corrupted data. The main implications include potential data corruption, unexpected program termination, and difficult debugging due to non-deterministic nature of threading. In severe cases, it could even cause system instability. To prevent this, proper synchronization mechanisms like mutexes or semaphores should be used to ensure safe access to shared resources.
