To avoid these issues, many languages such as Java or Python manage dynamic memory automatically using a technique called [_garbage collection_]. The idea is that the programmer never invokes `deallocate` manually. Instead, the programm is regularly paused and scanned for unused heap variables, which are then automatically deallocated. Thus, the above vulnerabilities can never occur. The drawbacks are the performance overhead of the regular scan and the probaby long pause times.
