-Wstringop-overflow=4 行为:使用“类型三”(type-three)的对象大小检查。 特性: 当任何数据成员发生溢出时发出警告。 当目标对象可能是多个对象之一时,使用最大对象的大小来决定是否发出警告。 与-Wstringop-overflow=3类似,可能会对一些良性代码发出警告。 应用场景:这是最严格的设置,适用于需要最大化内存安全检测...

这个错误信息表示你尝试将一个字节的数据写入到一个大小为0的内存区域。在C或C++等编程语言中,这意味着你试图访问或修改一个未分配或已被释放的内存空间,这通常会导致未定义行为,包括程序崩溃或数据损坏。 阐述可能导致这种错误的情况 数组或指针越界:当你尝试访问数组或指针指向的内存区域之外的内存时,可能会遇到这...
