Met this error when writing the code chart carefully searched, it turned out to be

m_pMatrix = new int[m_iCapacity];
   //初始化内部数据  将所有成员设置为0
memset(m_pMatrix, 0, m_iCapacity*m_iCapacity * sizeof(int));

Application memory allocation less
modified

m_pMatrix = new int[m_iCapacity*m_iCapacity];
   //初始化内部数据  将所有成员设置为0
memset(m_pMatrix, 0, m_iCapacity*m_iCapacity * sizeof(int));

Summary: This type of error, first check there are no new errors, most of the time in the application memory problems, leading to follow-up function can not operate normally
