However, dynamic compilation can still technically have compilation errors, [citation needed] although many programmers and sources may identify them as run-time errors. Most just-in-time compilers, such as the Javascript V8 engine, ambiguously refer to compilation errors as syntax errors since they check for them at run time. [1] [2]
A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
Multi-language tool for software verification. Applications range from coding rule validation, to automatic generation of testcases, to the proof of absence of run-time errors or generation of counterexamples, and to the specification of code matchers and rewriters based both syntactic and semantic conditions.

Polyspace is a static code analysis tool for large-scale analysis by abstract interpretation to detect, or prove the absence of, certain run-time errors in source code for the C, C++, and Ada programming languages. The tool also checks source code for adherence to appropriate code standards. [3]
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.
This example specifies a valid D function called "factorial" which would typically be evaluated at run time. The use of enum tells the compiler that the initializer for the variables must be computed at compile time. Note that the arguments to the function must be able to be resolved at compile time as well. [4]
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.
