opencv stack overrun 栈溢出

Question

Unhandled exception at 0x00E61A6C in testdll_1.exe: Stack cookie instrumentation code detected a stack-based buffer overrun.

虽然可以正常运行，但在程序结束时 } 会引起程序报错，即使是imshow一张图像也会导致内存越界，请问原因是初始化的问题吗？

头文件如下

    void set_morph2(int x, int y);//canny用，默认即可,竖向断裂

    void set_morph(int x, int y);//同正负，正数变粗，负数变细
    void set_morph_easy(int x);//x=1: 3,1--字体横向变细，x=2：-3，-1--字体横向变粗， x=3：1，1--不变

    void set_blocksize(int _C, int _blocksize = 31);//阈值 blocksize自适应区块大小，影响背景过滤程度，默认31，C需人工调整，白色字体C为负数，深色字体正数，影响噪点
    void set_blocksize_easy(int x);//0:字体无粘连，背景无线条，自动阈值， x=1：31，15--字体深色   2：31，-15--字体浅色，背景深色   3：31，4--字体深色但较细
