返回信息流这是出错地方的代码，在erase那句报错。我输出了m_mHarqRank2SINR中的数据，发现也确实包含 关键字（m_iHARQID, _iRankID），关键字对应的value也有，不明白为什么会不能删除。
map<pair<int, int>, vector<double> >::iterator it = m_mHarqRank2SINR.find(make_pair(m_iHARQID, _iRankID));
if (it != m_mHarqRank2SINR.end()) {
m_mHarqRank2SINR.erase(it);
} else {
cout<<"HARQRxStateMS can not erase data!"<<endl;
assert(false);
}
下面是查问题（free(): invalid next size）的时候遇到类似的错误，一个人的回答。
It means that you have a memory error. You may be trying to free a pointer that wasn't allocated by malloc (or delete an object that wasn't created by new) or you may be trying to free/delete such an object more than once. You may be overflowing a buffer or otherwise writing to memory to which you shouldn't be writing, causing heap corruption.
求各位大神指点，跪谢[ema23]
后面是报错提示的一大堆看不懂信息

单线程和多线程跑都会出错，不过具体单线程和多线程怎么实现的我就不太了解了。错误的好尴尬，完全不理解。大神有思路么？
