Pointer assigned to correct memory location not working| Vincenzo (5) |  |
| Hi, first of all, the code: RPC<uint32> local_catalog_address = remote_qp.get_local_catalog(); cout << "local_catalog_address: " << local_catalog_address << endl; Diagram *catalog; catalog = (Diagram*) (*local_catalog_address); cout << "catalog address: " << &catalog << endl; cout << "catalog is pointing to " << catalog << endl; cout << catalog->as_string(); local_catalog_address if the momery location of a Diagram object. When I print "catalog is point to ..." the address is the correct address (&(0x8b4fbe8) for example). I'm sure that the address is correct because I print it on the class containing the method get_local_catalog(), and the addresses match. I have a segmentation fault when I try to invoke the method as_string(), even if this method is working when used on the other class. Am I missing something??? Thanks in advance | |

| I'm not really sure (since I don't know what RPC<> is) but it looks like you're casting local_catalog_address to something it shouldn't be cast to. | |

| I undestand what you say. In my mind what I think is: If I have a pointer to an object, whatever it is, and I achieve the goal to make it point to an address where I know there is an istantiation of this object, I can use this pointer. Reading what you wrote, it seems that my reasoning is wrong. Is it? Thanks | |
