memory leak

(programming)
A leak in a program's dynamic store allocation logic that causes it to fail to reclaim memory in the heap after it has finished using it, eventually causing the program to fail due to lack of memory.

These problems were severe on older machines with small, fixed-size address spaces, and special "leak detection" tools were written to diagnose them.

The introduction of virtual memory made memory leaks a less serious problem, although if you run out of virtual memory, it means you've got a *real* leak!

See aliasing bug.

memory leak

A condition caused by a program that does not free up the extra memory it allocates. In programming languages, such as C/C++, the programmer can dynamically allocate additional memory to hold data and variables that are required for the moment, but not used throughout the program. When those memory areas are no longer needed, the programmer must remember to deallocate them.

When memory is allocated, but not deallocated, a memory leak occurs (the memory has leaked out of the computer). If too many memory leaks occur, they can usurp all of memory and bring everything to a halt or slow the processing considerably. In other environments, such as Java, the operating system allocates and deallocates memory automatically. Specifically allocating and deallocating memory, while error prone (in case one forgets to deallocate), allows the programmer more control over the computer's resources. See garbage collection.

In the recent years, model based testing has been gaining pace in various technical organizations, for its ability to detect memory leaks and conflicts that could otherwise cause a software to crash.
They consider such topics as the role of xiao (doing together) in moral reputation management and cooperation in urban China and Taiwan, memory leaks: local histories of cooperation as a solution to water-related cooperation problems, care as a bureaucratic lubricant: the role of female care workers in an old people's home in rural China, challenges to ethnic cooperation among Hong Kong Chinese in Scotland, and problems in the new cooperative movement: a window onto changing cooperation mechanisms.
They do this by injecting invalid, unexpected, or semirandom data into an interface or program and then monitoring for events such as crashes, undocumented jumps to debug routines, failing code assertions, and potential memory leaks.
Further investigation led to the conclusion that Microsoft Office files that included ActiveX controls were consistently causing memory leaks.
The first is through code reviews and code analysis; making make sure code is well maintained and that there are no memory leaks. Developers must be committed to eliminating and fixing code that slows them down--asking themselves 'is our testing code blocking the continuous integration workflow?, and 'what are the common recurring quality issues throughout our CI jobs?'.
Thus, the risk of memory leaks is significantly reduced because users no longer have to release unused memory manually.
