The ability to detect non-fatal errors is a major distinction between PurifyPlus and similar programs from the usual debuggers.By contrast, debuggers generally only allow the programmer to quickly find the sources of fatal errors, such as a program crash due to dereferencing a null pointer, but do not help to detect the non-fatal memory errors.
A continuous inspection engine that finds vulnerabilities, bugs and code smells. Also tracks code complexity, unit test coverage and duplication.

Some modern high-level programming languages are memory-safe by default [citation needed], though not completely since they only check their own code and not the system they interact with. Automatic memory management in the form of garbage collection is the most common technique for preventing some of the memory safety problems, since it ...
Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
The "sawtooth" pattern of memory utilization: the sudden drop in used memory is a candidate symptom for a memory leak. If the memory leak is in the kernel, the operating system itself will likely fail. Computers without sophisticated memory management, such as embedded systems, may also completely fail from a persistent memory leak.
Using non-owned memory: It is common to use pointers to access and modify memory. If such a pointer is a null pointer, dangling pointer (pointing to memory that has already been freed), or to a memory location outside of current stack or heap bounds, it is referring to memory that is not then possessed by the program. Using such pointers is a ...
50x photograph of magnetic core random access memory from a 4 KiB memory plane. In computing, a core dump, [a] memory dump, crash dump, storage dump, system dump, or ABEND dump [1] consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated ...
Typical resource leaks include memory leak and handle leak, particularly file handle leaks, though memory is often considered separately from other resources. [1] Examples of resources available in limited numbers to the operating system include internet sockets, file handles, process table entries, and process identifiers (PIDs). Resource ...
