App crashes only in xcode instruments

Question

I have a strange issue, I have developed an app , I analyzed the app from Xcode ie Xcode>Product>Analyze, then fixed any memory leaks I got. I ran the app in ipad simulator it worked fine, no crash nothing, ran it on an iPad device;no crash no errors nothing.

But when I tried to profile the app from instruments for memory leaks , during profiling there were no memory leaks, but at one stage when I load a modal view and then after Modal view dismissal the app crashes and instrument displays simulator session time out. What could be the problem ?

如果您有任何编译条件，例如： #ifdef DEBUG ... ，要在调试和发布之间打开/关闭功能，这可能会导致问题，因为Instruments使用Release配置并且常规Simulator运行使用Debug。
