Node setup with -debug, and binary not stripped for debugging.

Code changes include everything in TRB Vtree, + 'mod6_getdata_blocks_wrangler.vpatch'.

Also added this small bit of debugging code to EndMessage in net.h:

            if (addr.IsLocal())
            {   
                printf("XXX: From Local\n");
                //printf("XXX: vSend Size from TXs: %zu = (%zu - (%zu + %zu))\n", vSend.size(), vSend.end(), vSend.begin(), nMessageStart);
                printf("XXX: vSend Size from TXs (hex): %zx = (%zx - (%zx + %zx))\n", vSend.size(), vSend.end(), vSend.begin(), nMessageStart);
                printf("XXX: vSend Size from TXs (dec): %zu = (%zu - (%zu + %zu))\n", vSend.size(), vSend.end(), vSend.begin(), nMessageStart);

                if ((vSend.end() - (vSend.begin() + nMessageStart)) >= 0x10000)
                {   
                    printf("Size large: %zu = (%zu - (%zu + %zu))\n", (vSend.end() - (vSend.begin() + nMessageStart)), vSend.end(), vSend.begin(), nMessageStart);
                }
                if ((vSend.end() - (vSend.begin() + nMessageStart)) >= 0x100000000)
                {   
                    printf("Size wedge: %zu = (%zu - (%zu + %zu))\n", (vSend.end() - (vSend.begin() + nMessageStart)), vSend.end(), vSend.begin(), nMessageStart);
                }
            }

As well as in the 'getdata' section for TX's in main.cpp:

            else if (inv.IsKnownType())
            {   
                // Send stream from relay memory
                CRITICAL_BLOCK(cs_mapRelay)
                {   
                    map<CInv, CDataStream>::iterator mi = mapRelay.find(inv);
                    if (mi != mapRelay.end())
                    {   
                        if (pfrom->addr.IsLocal())
                        {   
                            printf("XXX (main.cpp): CDataStream Size: %zu | %zx\n", (*mi).second.size(), (*mi).second.size());
                        }
                        pfrom->PushMessage(inv.GetCommand(), (*mi).second);
                    }
                }
            }

Same test as 'mod6_wedger_tx_test1.log', with just the added single printf statement. (See above).

It certainly did not wedge.  Node is responding to RPC commands, is up-to-date with 622932 blocks, and 22 connections.

A bit more analysis needs to be done.  Saving the log file to 'trb_debug_wedger_tx_test3.log'.
