帮我看看这段代码，很简单的功能，为什么会错呀

[Boy_Vc]

UINT datalenth = 0;
GetFileDataLenth(m_pFromFile,&datalenth);
BYTE* chToDataBuffer = new BYTE[szDataCount];
BYTE* pchDataBuffer = new BYTE[szDataCount];
UINT nBytesAllRead = 0;
DWORD nBytesRead = 0;
int count=0;
while( nBytesAllRead < datalenth)
{
size_t bytesToRead = (size_t) min(szDataCount,size_t(datalenth - nBytesRead));
m_pFromFile->Read(pchDataBuffer, bytesToRead，&nBytesRead);
int flag = 0;
int left = szDataCount%LPC_FRAME_BETWEEN;
for(flag=0;flag<szDataCount-left;flag += LPC_FRAME_BETWEEN)
memcpy( (chToDataBuffer+flag), (pchDataBuffer+flag)，
LPC_FRAME_BETWEEN*2);// 注释掉就不会发生（2）出错 }

delete[] chToDataBuffer;
delete[] pchDataBuffer;//(2) 为什么这里会错

return TRUE;

建议：
BYTE* pchDataBuffer = new BYTE[szDataCount];
BYTE *tempBuf = pchDataBuffer;

pchDataBuffer = tempBuf;
if (pchDataBuffer != NULL)
delete[] pchDataBuffer;

有数据还在内存中没读出来吧

[Boy_Vc]

我必须要两个buffer的，哪个数据还没读出来呀？

没看明白,不过
dele
te[] pchDataBuffer;//(2) 为什么这里会错
应该是pchDataBuffer或已被删除,或已被破坏了
看看它的最后四后面的四个字节是不是ff,ff, ff,ff
