大家有什么方法能确定是哪段代码非法修改啦内存？
环境：
windows xp sp2
中文版， Visual Studio 2005 Professional Edition。
Output window:
HEAP[fxecgSUD.exe]: Heap block at 00E4BF10 modified at 00E4BEFC past requested size of ffffffe4
Windows has triggered a breakpoint in fxecgSUD.exe.
This may be due to a corruption of the heap, and indicates a bug in fxecgSUD.exe or any of the DLLs it has loaded.
The output window may have more diagnostic information
出错位置：(出错位置不确定)
AFX_MODULE_THREAD_STATE* AFXAPI AfxGetModuleThreadState()

出错位置 AFX_MODULE_THREAD_STATE* pResult=AfxGetModuleState()->m_thread.GetData();
ENSURE(pResult != NULL);
return pResult;
}
