liblinphone call on terminate skips End or Error state and enters into Released state #199

I am developing a c++ console program using c++ wrapper of liblinphone. I am able to perform a video call, however, when I terminate the ongoing call, my application crashes. From the logs I figured out the problem, which was liblinphone-fatal-Attempt to move CallSession [03501C44] to Released state while it was not previously in Error or End state, aborting

While hanging up the call, first the call is entering to Released state, I am getting above log then after a few millis call is entering into End state.

Any idea on what could be the possible reason for this.

Following is the code I used to perform video call and to terminate the call, I am following linphone-desktop repository and Csharp turtorials for this code::

void LinphoneManager::Call(string sipAddress) {
shared_ptr<Address> address = storedCore->interpretUrl(sipAddress);
shared_ptr<linphone::CallParams> params = storedCore->createCallParams(nullptr);
params->enableVideo(true);
params->setProxyConfig(storedCore->getDefaultProxyConfig());

currentCall = storedCore->inviteAddressWithParams(address, params); // Current call declared as class members ( shared_ptr<Call> currentCall ;)
currentCall->enableCamera(true);   

//After call is connected I am adding Dtmf listener to call
shared_ptr<DtmfListener> DTMF = make_shared<DtmfListener>(callBack);
currentCall->addListener(DTMF);
}

void LinphoneManager::callHangUp() {
    managerLogger->info("Inside call hangup");

    shared_ptr<linphone::Address> address = storedCore->interpretUrl(sipAddToCall);
    if (!address)
        managerLogger->warn("Cannot terminate Call. The address cannot be parsed : {}", sipAddToCall);
    else {
        std::shared_ptr<linphone::Call> call = storedCore->getCallByRemoteAddress2(address);
        if (call) {
            call->terminate();
        }
        else {
            managerLogger->warn("Cannot terminate call as it doesn't exist : {}",  sipAddToCall);
        }
    }
}

Following are the logs generated after call Hang up ::
