Description
请提出你的问题 Please ask your question
我用paddle2.6跑模型时遇到过最后一个epoch评估阶段访问了nullptr的raw_stream和raw_event（不是封装的那个stream和event）而导致段错误的bug，怀疑是多线程中主线程已经销毁了这些资源，但子线程中还在调用。所以想请教下paddle多线程场景资源释放的流程是什么样的，希望飞桨的老师能帮忙解答，谢谢！

Research direction
Start by tracing the Paddle 2.6 code paths that create and release raw_stream and raw_event during multithreaded model evaluation. The issue names no files or tests; completion would require reproducing the final-epoch nullptr access and documenting or correcting the resource-lifetime behavior.
