C++ std::bad_alloc error

我正在开发一个C++程序(C++ 98(。它读取包含大量行(10000 行(的文本文件。这些是制表符分隔的值，然后我将其解析为矢量对象的矢量。但是它似乎适用于某些文件(较小(，但是我的一个文件给了我以下错误(该文件有10000行，为90MB(。我猜这是一个与内存相关的问题？你能帮帮我吗？

错误

  what():  std::bad_alloc
Abort

法典

void AppManager::go(string customerFile) {

    for (unsigned int i = 0; i < vals.size();i++){
        cout << "New Onenn";
        for (unsigned int j = 0; j < vals[i].size(); j++){
            cout << vals[i][j] << endl;
