大家帮我看看，我NEW过的内存，delete了啊。为什么会有内存泄露？

char *aabb[]={"w"};
AddItem( aabb,1)；//这么调用（1）

void taggeneralNod_T::AddItem( char * pStr[] ,int nLength)
{
nNumList=nLength;

if( nNumList > 0)
{
Allocate(nNumList);
}

for( int nColumn = 0; nColumn < nNumList; nColumn++ )
{
ppEnumList[ nColumn ] = new TCHAR[lstrlen( pStr[nColumn] ) + 1 ]; // 《---- 内存泄露（2）
(void)lstrcpy( ppEnumList[ nColumn ], pStr[nColumn] );
}
}

void taggeneralNod_T:: Allocate(int nNum)
{
nNumList = nNum;

ppEnumList = new LPTSTR[nNum];

for( int i = 0 ; i < nNum ; i ++ )
{
ppEnumList[i] = NULL;
}
}

void taggeneralNod_T::Release()
{
if ( ppEnumList != NULL )
{
for( int i = 0 ; i < nNumList ; i ++ )
{
if ( ppEnumList[i] != NULL )
{
delete [] ppEnumList[i];
ppEnumList[i] = NULL;
}
}
delete [] ppEnumList;
ppEnumList = NULL;
}
nNumList = 0;
}
内存泄露提示如下：（3）
