程序在VS2008中运行良好，在程序的最后在VS2010中抛出异常

我正在使用二进制/直接访问写入一个文件。在2008年像一个符咒一样工作，但在2010年运行时在第128行创建了一个异常：Unhandled exception at 0x535dad54 (msvcp100d.dll) in HovedProsjekt.exe: 0xC0000005: Access violation writing location 0xfeeefeee.

单击错误将转到xutility，第201行：_Pnext != 0; *_Pnext = (_Pnext)->_Mynextiter)是下一个要执行的行。我看了一下微软的"突破性更改"页面，运气并不好。我正在用明文复制/粘贴整个代码，所以没有过时的库。我已经尝试了启用和禁用_HAS_ITERATOR_DEBUGGING和_SECURE_SCL的所有组合。我根据另一位用户的建议更改了我的问题，以精简我的代码。
