Thank you, Eliot, for your reply. 🙏
I solved it, but still need to understand the cause. *

*This is the full story: *
I defined an STL queue of pointers to Packets to store the packets for further
resending.
std::queue<PacketPtr> pktQueue;
It is defined as a member of the memory object class.
And I'm debugging before and after this call
Inside "CoherentXBar::recvTimingReq":
success = memSidePorts[mem_side_port_id]->*sendTimingReq*(pkt);
*Before* the call, it appears that the Packet contains all correct fields (i.e. the address and
flags etc.)
*After * the call it fails to assert the "VALID_ADDR".
I *solved *this problem as the following:
Inside the newmemory simulation object, when inserting a new blocked packet:
Before:
blockedPacketQueue.push(pkt)
After:
PacketPtr pPkt= new Packet(pkt,false,true);
pktQueue.push(pPkt);
I still can't figure why the first way doesn't work !
Well, I still wonder if the packet is getting freed
(or something) down in the sendTimingReq actions.
Among other things, I wonder if you are trying to save
it *and* it is getting responded to, which would turn
it into a response, etc.
Copying it like that is fixing the symptom, but I am
not sure it is fixing the real problem.
