この投稿を確認し、言及されている提案を試しましたが、メモリリークが発生する代わりにsegmentation faults
.
これは、リークの原因となるコードです。
class RecordWithKey : public VarLengthRecord {
protected:
Key* Key;
};
class Key {
protected:
KeyType keyType;
Key* Keys[2];
};
RecordWithKey& RecordWithKey::operator=(const RecordWithKey& other)
{
if (this != &other)
{
this->Key = new Key(*(other.Key));
/* ... other code ... */
}
return *this;
}
RecordWithKey::~RecordWithKey()
{
delete(Key);
Key = NULL;
}
Key::~Key()
{
for (unsigned int i = 0; i < KEY_TYPES; i++)
{
delete(Keys[i]);
Keys[i] = NULL;
}
}
Key& Key::operator =(const Key& other)
{
if (this != &other)
{
this->keyType= other.keyType;
for(unsigned int i=0;i<KEY_TYPES;i++)
(*Keys[i]) = (*other.Keys[i]);
}
return (*this);
}
RecordWithKey::RecordWithKey()
:VarLengthRecord()
{
Key = NULL;
}
RecordWithKey::RecordWithKey(const RecordWithKey& other)
: VarLengthRecord(other)
{
Key = new Key(*(other.Key));
}
Key::Key()
{
this->keyType = TYPE_STRING; //default type
this->Keys[TYPE_NUMERIC]= new NumericKey;
this->Keys[TYPE_STRING]= new StringKey;
}
Key::Key(const Key& other)
{
this->keyType = other.keyType;
this->Keys[TYPE_NUMERIC]= new NumericKey;
this->Keys[TYPE_STRING]= new StringKey;
if (this->keyType == TYPE_NUMERIC)
{
int Key;
other.get_Key(Key);
set_Key(Key); //there is no "new" inside of this
}
else if (this->keyType == TYPE_STRING)
{
std::string Key;
other.get_Key(Key);
set_Key(Key); //there is no "new" inside of this
}
}
