Many other runtime errors exist and are handled differently by different programming languages, such as division by zero errors, domain errors, array subscript out of bounds errors, arithmetic underflow errors, several types of underflow and overflow errors, and many other runtime errors generally considered as software bugs which may or may ...
Dereferencing any of these variables could cause a segmentation fault: dereferencing the null pointer generally will cause a segfault, while reading from the wild pointer may instead result in random data but no segfault, and reading from the dangling pointer may result in valid data for a while, and then random data as it is overwritten.
The proto-runtime toolkit was created to simplify the creation of parallel runtime systems. [ 3 ] In addition to execution model behavior, a runtime system may also perform support services such as type checking , debugging , or code generation and optimization .
Astrée ("Analyseur statique de logiciels temps-réel embarqués" [1]) is a static analyzer based on abstract interpretation.It analyzes programs written in the programming languages C and C++, and emits an exhaustive list of possible runtime errors and assertion violations.
The terminology runtime verification was formally introduced as the name of a 2001 workshop [2] aimed at addressing problems at the boundary between formal verification and testing. For large code bases, manually writing test cases turns out to be very time consuming. In addition, not all errors can be detected during development.
For example, some language features that can be performed only (or are more efficient or accurate) at runtime are implemented in the runtime environment and may be invoked via the runtime library API, e.g. some logic errors, array bounds checking, dynamic type checking, exception handling, and possibly debugging functionality. For this reason ...
Computer systems that use time for critical computations may encounter fatal errors if the year 2038 problem is not addressed. Some applications that use future dates have already encountered the bug. [4] [5] The most vulnerable systems are those which are infrequently or never updated, such as legacy and embedded systems.
