SecureSocketImpl::currentSession() regression since 1.12.4

[micheleselea]

when we switch from 1.12.4 to 1.12.5 I think the function SecureSocketImpl::currentSession() was changed.
in 2023 we discuss about implementing SecureSocketImpl::currentSession() link this

Session::Ptr SecureSocketImpl::currentSession()
{
	if (_pSession) return _pSession;
	if (_pSSL)
	{
		SSL_SESSION* pSession = SSL_get1_session(_pSSL);
		if (pSession)
		{
			if (_pSession && pSession == _pSession->sslSession())
			{
				SSL_SESSION_free(pSession);
				return _pSession;
			}
			else return new Session(pSession);
		}
	}
	return 0;
}

because sometimes happened currentSession() return always nullptr.
since 1.12.5 the function was as before

Session::Ptr SecureSocketImpl::currentSession()
{
	return _pSession;
}

the same in 1.14.1

@micheleselea Yes, we are also facing the same issue. Reverting this helped us.
