I was just wondering whether or not poor use of memory management can lead to hardware problems. Reason I am asking is because I a lot of people warn or caution against using placement new unless you know what you are doing. I am reluctant on using placement new for experimentation/learning purposes because I am anxious that I might mess up my hardware or operating system. Do I have anything to worry about by just trying or should I stay put until I have a good understanding of placement new and memory management in general.
Nah. If you have any kind of recent OS your program will be unable to do anything except crash itself; the OS will stop you from messing with anything else.
