A sudden memory jump in TinyXML during multithreading can happen due to improper thread safety when multiple threads access or modify the same TinyXML data structures. TinyXML itself is not thread-safe, meaning simultaneous operations on shared objects can lead to issues like memory corruption or unexpected memory allocations. Potential Causes: Concurrent Memory Allocations: Multiple threads allocating memory for TinyXML nodes, elements, or attributes without proper synchronization can cause spikes...
