Description

This should be some memory out of bounds. I don't have a good solution for this problem. I would like developers to confirm it. Thank you
. Also, this is a problem that only occurs with frequent use.

定位到：
MMRGBHex ncolor = MMRGBHexAtPoint(needle, scan.x, scan.y);
这个位置报错的， Exception 0xc0000005 0x0 0xc0005151b6 0x67f792 PC=0x67f792
通过分析观察应该是因为协程的并发速度比较快导致内存地址发生了变化或者什么其他未知原因
这个问题不知道该怎么解决我已经对

// 检查scan.x和scan.y是否在needle的边界内，如果超出边界，则返回错误
            if (scan.x < 0 || scan.x >= needle->width || scan.y < 0 || scan.y >= needle->height) {
                return 0;
            }
            // 检查offset.x + scan.x和offset.y + scan.y是否在haystack的边界内
            if (offset.x + scan.x < 0 || offset.x + scan.x >= haystack->width || offset.y + scan.y < 0 || offset.y + scan.y >= haystack->height) {
                // 如果超出边界，返回0
                return 0;
            }
            //再次检查needle是否为空，如果为空，则返回错误
            if (needle == NULL) {
                return 0;
            }
            // 获取needle和haystack在当前扫描点的颜色
            // 进行比较，看是否被修改
            if(old_needle != needle || old_haystack != haystack){
                // 如果 needle 或者 haystack 已被修改，返回0
                return 0;
            }

还是未能解决该问题
