Software development. A software bug is a bug in computer software . A computer program with many or serious bugs may be described as buggy. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing ). Software bugs have been linked to disasters.
A race condition or race hazard is the condition of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events, leading to unexpected or inconsistent results. It becomes a bug when one or more of the possible behaviors is undesirable.
Although this will not work in all cases, for example when calling the wrong subroutine, it is the easiest way to find the problem if the program uses the incorrect results of a bad mathematical calculation.
The first program to experience the out-of-memory may or may not be the program that has the memory leak. Some multi-tasking operating systems have special mechanisms to deal with an out-of-memory condition, such as killing processes at random (which may affect "innocent" processes), or killing the largest process in memory (which presumably is ...
Undefined behavior. In computer programming, undefined behavior ( UB) is the result of executing a program whose behavior is prescribed to be unpredictable, in the language specification to which the source code adheres. This is different from unspecified behavior, for which the language specification does not prescribe a result, and ...
Lint (software) Lint is the computer science term for a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. [1] The term originates from a Unix utility that examined C language source code. [2] A program which performs this function is also known as a "linter".
Bug (engineering) In engineering, a bug is a design defect in an engineered system that causes an undesired result. Although used exclusively to describe a technical issue, bug is a non-technical term; applicable without technical understanding of the system. The term bug applies exclusively to a system that is (human) designed; not to a ...
If the affected program is running with special privileges, or accepts data from untrusted network hosts (e.g. a webserver) then the bug is a potential security vulnerability. If the stack buffer is filled with data supplied from an untrusted user then that user can corrupt the stack in such a way as to inject executable code into the running ...
