Dangling pointers (accessing memory that is out of scope--usually returned from a function) 4.) Double free (deleting memory twice). In this lesson I also show you how to use the address sanitizer as part of the compiling process to help detect these problems. For Linux users, I also show valgrind (pronounced val-grinn, like the name 'Val' and a grine like a smile).
