“valgrind invalid read of size 1”错误是Valgrind内存检测工具报告的一种错误,表示程序试图读取一个大小为1字节的内存区域,但这个区域并未被分配或已经被释放,从而导致了非法访问。这通常意味着程序中存在内存管理问题,如越界访问、野指针使用等。 2. 可能导致“valgrind invalid read of size 1”错误的原因 数组...

所以我在使用Valgrind时得到了这个错误:读取大小为1的无效数据。这是程序中出现错误的部分。至于程序是做什么的。msgArr是一堆以字符串形式存储的整数。然后,我从**msgArr中提取int值,并将其用作从**wordArr中获取字符的索引。我得到的字符,我存储他们**解码。==31064== Invalid read of size 1 ==31064== ...
