Learn about the new features from OpenMP 5.1 and OpenMP 5.2 which are implemented in GCC 12.

Could your perfectly running program blow up someday? Learn different types of behavior in the standard and what helps make a correct C or C++ program.

Breakpoints are the most commonly used (and underused) debugging event in a debugger. This article discusses the breakpoint features that GDB offers developers, and shows how to use breakpoints effectively.

Interactions between libraries can cause embarrassing crashes during shutdown, but OpenSSL provides a robust shutdown procedure.

Discover how flexible array members offer convenience and improve performance, and how compiler complexities are mitigated.

Discover the gains and costs of GCC’s enhanced runtime buffer overflow protection. Level 3 _FORTIFY_SOURCE preprocessor macro may detect more buffer overflows, but there’s a cost.
