什么可能导致 mscorwks!ThreadpoolMgr::FireTimers 发生访问冲突？
以下访问冲突每隔几天就会使我的应用程序崩溃。可能是什么原因造成的？

The following access violation is crashing my application every few days. What could be causing this?

c0000005异常一般是内存异常。您正在尝试访问内核空间中的内存，或者您对该内存区域没有权限。不幸的是，您提供的信息不足以提供进一步的帮助。至少您应该提供堆栈跟踪，更好地提供“analyze -v”的输出。
查看最后一条汇编指令，我可以看到它尝试复制地址 0 处的数据，因此此异常只是由于尝试取消引用地址 0 引起的。
The c0000005 exception is generally a memory exception. You are trying to access memory that is either in the kernel space or you have no permission on the memory area. The information that you provide is unfortunately not sufficient to help any further. At least you should provide the stack trace, better the output of 'analyze -v'.
And looking at the last assembly instruction I can see it tries to copy data at address 0, so this exception is simply caused by trying to dereference adress 0.
