请教关于QT中New BYTE内存释放的问题 - QTCN开发网

我通过 new BYTE[szSize]的方式创建了struct指针，然后把它们加入QList，当整个对象释放的时候，再遍历QList逐一delete指针，但是每次释放到第2个指针对象时均报以下错误：
HEAP[xxx.exe]: Invalid address specified to RtlValidateHeap( 000000FD6A3E0000, 000000FD7367C330 )
代码如下：

复制代码

// XObject.h
typedef struct _MEM_INFO
{
DWORD Index;
UINT Type;
char Info[INFO_SIZE+1];
...
} MEM_INFO, *P_MEM_INFO;
typeof struct _STRUCT_TEST
{
P_MEM_INFO pMemInfo;
...
}STRUCT_TEST;
...
class XObject //XObject 不是继承自 QObject！
{
private:
QList<STRUCT_TEST> testList;
...
};
// XObject.cpp
void XObject::Create()
{
for(int i=0;i<10;i++){
P_MEM_INFO pInfo = (P_MEM_INFO) new BYTE[sizeOfMeminfo];
...
STRUCT_TEST test;
test.pMemInfo = pInfo;
infoList.append(test);
}
...
}
// 析构
XObject::~XObject()
{
for(int i=0;i<infoList.length();++i){
STRUCT_TEST *pTest = &(infoList[i]);
if(pTest->pMemInfo){
delete pTest->pMemInfo; // i == 1 时出错：HEAP[xxx.exe]: Invalid address specified to RtlValidateHeap( 000000FD6A3E0000, 000000FD7367C330 )
pTest->pMemInfo = NULL;
}
}
}
