{{See also|Runtime error}}
* [[Null pointer]] dereference.
* Using an [[uninitialized variable]].
* Using an otherwise valid instruction on the wrong [[data type]] (see [[packed decimal]]/[[binary-coded decimal]]).
* [[Access violation]]s.
* Resource leaks, where a finite system resource (such as [[memory leak|memory]] or [[handle leak|file handles]]) become exhausted by repeated allocation without release.
* [[Buffer overflow]], in which a program tries to store data past the end of allocated storage. This may or may not lead to an access violation or [[storage violation]]. These are frequently [[security bug]]s.
* Excessive recursion which—though logically valid—causes [[stack overflow]].
* Use-after-free error, where a [[Pointer (computer programming)|pointer]] is used after the system has freed the memory it references.
* Double free error.
