Given something function like this:
void process() {
std::shared_ptr<Receiver> receiver(std::make_shared<Receiver>());
Command *cmd1 = new InfoCMD(receiver,10);
cmd->Execute();
delete cmd;
DELAY_MS(1000);
Command *cmd2 = new InfoCMD(ble,20);
cmd2->Execute();
DELAY_MS(1000);
delete cmd2;
}
Being the base class BLECommand like this:
class Command {
protected:
std::shared_ptr<Receiver> pReceiver_;
public:
Command(std::shared_ptr<Receiver> receiver) : pReceiver_(receiver) {}
virtual ~Command() {}
virtual void Execute() const = 0;
};
I have a error due a double delete BLEReceiver objetct (ble) and I don't have idea because happens that. The shared_ptr class should avoid this.
For debug this issue, I have put a print in the destructor of BLEReceiver class, and this is the output on the device console:
W (9932) Receiver: delete receiver
W (10872) Receiver: delete receiver
CORRUPT HEAP: multi_heap.c:172 detected at 0x3ffbddcc
abort() was called at PC 0x4008d873 on core 0
Setting breakpoint at 0x40089a0a and returning...
Any idea to solve this problem? Thanks in advance.
Edit:
The declaration of base class is this:
class InfoCMD : public Command {
private:
uint32_t info;
public:
InfoBLECMD(std::shared_ptr<BLEReceiver> receiver,uint32_t info) :
Command(receiver),
info(info){};
~InfoCMD(){}
void Execute() const;
};
And the definition is something like this:
void InfoCMD::Execute() const{
this->pReceiver_->setData(this->info);
this->pReceiver_->SendData();
}
