问题：程序奔溃，报错：线程 0x9e90 已退出,返回值为 -1073740777 (0xc0000417)。
过程：调试程序，在退出某个函数时，程序异常退出，F11跟进，发现是vector变量释放时导致的奔溃。

The _CrtIsValidHeapPointer function is used to ensure that a specific memory address is within the local heap. The local heap refers to the heap created and managed by a particular instance of the C run-time library. If a dynamic-link library (DLL) contains a static link to the run-time library, it has its own instance of the run-time heap, and therefore its own heap, independent of the application's local heap. When _DEBUG is not defined, calls to _CrtIsValidHeapPointer are removed during preprocessing.
由于dll独立于程序，外部无法释放该dll中的堆栈空间。
本次无法释放的vector变量的空间由OpenCV函数imencode(".jpg", src, buf, param)申请，无法在外部释放。
文章也指出另一可能是VS的版本和OpenCV的版本不同造成。
解决：在使用imencode前，未vector变量分配空间std::vector<BYTE> buf = std::vector<BYTE>(DataSize);
