废话不多说,先看下面一段代码#include <iostream>#include using namespace std;class A{public:typedef std::map<int> myMap;void mapInsert(int i, string s){map.insert(std::make_pair(i, s));}void deleteMap(){for (myMap::iterator it = map.begin(); it != ma
Dear Sir or Madame, I came across a Valgrind error message that is related to the use of Fortran pointers. See below for a minimal testcase.

"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...
