Using the elastic nodes example I have put a breakpoint on the line

Node *node2 = new Node(this);

line in graphwidget.cpp and then when that breakpoint gets hit I try to add a watchpoint for the node1 variable by right-clicking and selecting add breakpoint. When I put the address in the debug log shows:

32watch *0x10396ce60
>&"watch *0x10396ce60\n"
dATTEMPT SYNC
>32^done,wpt={number="4",exp="*4355182176"}
dCANNOT PARSE WATCHPOINT FROM 

Although my understanding is that this is how it should be done. If this is not the case, then the documentation should be updated to make it clearer what is and is not possible when setting watchpoints.
