| Cppcheck 2.19.0 Dec 22, 2025 |
Major bug fixes & crashes: Crash in CheckClass::checkConst() fuzzing crash (assert) in Token::update_property_info() Crash in checkConstVariable() Crash in valueFlowLifetimeClassConstructor() GUI: scratch pad crash Assert failure in getParentValueTypes() Crash in simplecpp::Macro::expand() crash in Tokenizer::simplifyCPPAttribute() New checks: Detect zero initialization of unions in which its largest member is not declared as the first one. Depending on the compiler, there's no guarantee that the complete union will be zero initialized in such scenarios leading to potential access of uninitialized memory. Added warning when main() throws an exception C/C++ support: Fixed syntax error for C++23 lambda without parameter clause Added support for typeof and __typeof operators GUI: Fix bug: checks multiple configurations even though user provides defines Changed interface: some preprocessorErrorDirective and syntaxError errors got more specific error IDs. Removed deprecated platforms unix32-unsigned and unix64-unsigned Improve progress value Added float bits support in platform configuration Fixed --showtime not accounting for addons Performance: Introduced cache for followAllReferences() calls Infrastructure & dependencies: Removed deprecated support for builds with Qt5. Added make variables CXXOPTS and LDOPTS to extend existing CXXFLAGS and LDFLAGS. Added make variables CPPOPTS to extend existing CPPFLAGS. CPPFLAGS are not longer being passed to the linker command for cppcheck and testrunner. Updated Qt to 6.10.0 (official Windows release only). The official Windows binary is now built against Boost 1.89 for increased performance. Updated to simplecpp 1.6.2 The Visual Studio builds not longer set the WIN32 define. Added DISALLOW_PROCESS_EXECUTOR for building without fork(). |

The already deprecated support for qmake will be removed in Cppcheck 2.16 - please use CMake instead. Other: Add support for 'CLICOLOR_FORCE'/'NO_COLOR' environment variables to force/disable ANSI color output for diagnostics.
