关于内存delete报错的问题，以下代码在最后delete的时候

Question

（safe_deletevec是宏定义，如果指针不等于NULL，就删除并置NULL），就会报错，说是写入冲突，应该没有越界，可是就是想不通为什么出错，麻烦各位给些建议

short Nobone=m_sMinValue+50;
int m_nValueMax=0;
for(int i = 0; i < m_nOriImagePiece; i++)
{
int k = i*m_nWidth*m_nHeight;
for (int m = 0; m < m_nHeight; m++)
{
int v = m*m_nWidth + k;
for (int n = 0; n < m_nWidth; n++)
{
int a = ((short*)m_pProcessArray->GetDcmArray()[i]->GetData())[m_nWidth*m + n];
if (a>Nobone)
{
short m_nRadi = EDTdate[v+n];
if (m_nRadi>m_nValueMax)
m_nValueMax = m_nRadi;
}
}
}
}

m_nValueMax = m_nValueMax + 1;
short* occurs = new short[m_nValueMax];
memset(occurs , 0 ,sizeof(short)*m_nValueMax);

for(int i = 0; i < m_nOriImagePiece; i++)
{
    int k = i*m_nWidth*m_nHeight;
    for (int m = 0; m < m_nHeight; m++)
    {
        int v = m*m_nWidth + k;
        for (int n = 0; n < m_nWidth; n++)
        {
            int a = ((short*)m_pProcessArray->GetDcmArray()[i]->GetData())[m_nWidth*m + n];
            if (a>Nobone)
            {
               short m_nRadi = EDTdate[v+n];
               occurs[m_nRadi] = 1;
            }
        }
    }
}

numRadii = 0;
for (int i=0;i<m_nValueMax;i++)
{
    if (occurs[i])
        numRadii++;
}
//make an index of the distance-squared values
short* distSqIndex = new short[m_nValueMax];
memset(distSqIndex,0,sizeof(short)*m_nValueMax);
short* distSqValues = new short[numRadii];
memset(distSqValues,0,sizeof(short)*numRadii);
int indDs = 0;
for (int i=0;i<m_nValueMax;i++)
{
    if (occurs[i])
    {
        distSqIndex[i] = indDs;
        distSqValues[indDs++]=i;
    }
}
Safe_DeleteVec(occurs);

检查两个地方：
1. short m_nRadi = EDTdate[v+n];得到的m_nRadi是否可能越界
2. occurs指向数组，删除时应该是delete[] occurs而不是delete occurs
希望对你有帮助。
