    Funny how you apply this argument here. I would suggest the exact same thing but in reverse. Return by value, and profile it to make sure it's not being "stupid."

    It took me a long, long time to realize that pointers suck. Maybe there is hope for you.

    Pointers suck when not wrapped in smart pointers
    That's my experience. Most of the "access violation" I get is with complex, non-C++ish code, such as managing buffers and pointers by hand (which I do avoid).
    Mostly it's old code, written many years ago or so. We improve all the time!

    No, I do believe it can do it, but I don't know how or when.
    This may be applicable to you, though it pertains to the 2005 version of Visual C++:

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    They suck even then. Just a tiny bit less. Value semantics rule.
    All the buzzt!
