我以某种方式破坏了内存，因为我的程序在随机位置崩溃而没有错误。
我将valgrind与--leak-check=full结合使用，并与-O0 -g一起编译，并且它检测到的第一个问题是int main()中的第一行
cout << "reading file" << endl;
与
==5089== Warning: client switching stacks? SP change: 0x7ff0004f8 --> 0x7feb7de10
==5089== to suppress, use: --max-stackframe=4728552 or greater

==5089== Address 0x7feb7de08 is on thread 1's stack
它继续

指向
ifstream config_file("file");
几乎每一行都有错误。
是什么原因造成的？
最佳答案
我想我炸了我的第一叠!
