ahhh! that would explain that! doesn't one love the power and the unsafeness of C/C++? (there's an easy virus: ((char*)0) = "CORRUPT THIS DATA!!!!"; )

Actually, if you're running as a normal process on a modern operating system, that will only crash the individual program that did the bad access. Like in Windows when you see "X has encountered a problem and needs to close... ", many times the reason it needs to close is because of bad memory accesses. On a *nix box you'll see something on the screen saying 'segmentation fault'.

Now of course, if you're running in the kernel and make a bad memory access, then the system will generally crash, since theres nothing to protect you there. Incidentally, our programs are running as a kernel module on the cRio...

Pointers are a great and terrible thing. To the point that I've worked on many projects at work where the use of non-smart pointers is strictly prohibited. Simply put, 90% of us aren't smart enough to use them effectively without shooting ourselves in the foot (and I am definitely a member of that majority!)
