在使用标准向量函数时引发'std::bad_alloc'实例后调用的终止

我正在做一项任务，要求我们为现实游戏模拟"消除投票"程序。为此，我们使用一个类(Vote(来记录要消除的玩家的名称，另一个(Voting(不会在任何地方实例化，因为它的成员是静态的(我们需要它们(。投票存储在投票类内的向量上。

问题是，即使我使用push_back函数将选票存储在向量中，在运行程序几次后，我也得到了一个带有what(): basic_string::_M_create的std::length_error。关闭它并重新运行后，我第一次收到类似标题上的错误(std::bad_alloc(。

有什么想法吗？我怀疑这与矢量未正确释放内存有关，但我不确定。

我的代码(投票.h(：

#ifndef VOTING_H_INCLUDED
#define VOTING_H_INCLUDED
#include <vector>
#include <map>
#include "Vote.h" //ignore this one
#include "Team.h" //this one too
class Voting

public:
static vector <Vote> votes; //votes cast during voting procedure

static void votingProcess(Team &team); //the whole voting procedure
