错误：map / set iterator not dereferencable

Question

我遇到了食人魔的问题。当我启动渲染器（OpenGL或DirectX）时，我收到错误：

Debug Assertion Failed! C: \ windows \ system32 \ msvcp110d.dll File:
C: \ Program Files (x86) \ Microsoft Visual Studio 11.0 \ VC \ include
\ xtree <- (i dont have anything in this path) Line: 237

Expression: map / set iterator not deferencable

以下是代码：
