"valgrind invalid read of size"错误是Valgrind工具在运行时检测到的内存访问违规问题。这个错误表明你的程序尝试读取的内存区域是无效的,即该内存区域并未被你的程序所分配,或者已经被释放。size指的是尝试读取的字节数。 2. 可能原因 越界访问:访问数组或字符串时超出了其分配的内存范围。 使用未初始化的指针:指...

1 什么是内存泄漏 c语言中，需由开发者负责内存的申请和释放，内存泄漏是指开发者在程序中使用动态内存分配函数xxlloc在堆(heap)上申请内存，内存在使用完毕后未使用free函数释放，那么这块内存在程序退出前都不能再次使用，导致内存使用逐渐增大，直至耗尽，程序异常退出。 xxlloc函数指mal ...
