`cppcheck` can, in some cases, construct an invalid parse tree. http://build.ros2.org/user/rotu/my-views/view/CycloneDDS/job/Fci__nightly-cyclonedds_ubuntu_focal_amd64/lastCompletedBuild/testReport/rclcpp/cppcheck/error__internalAstError__src_rclcpp_clock_cpp_159_/ ``` - rclcpp.cppcheck error: internalAstError (src/rclcpp/clock.cpp:159) <<< failure message Syntax Error: AST broken, 'if' doesn't have two operands. >>> ``` This error sounds like a syntax error, but is in fact, not. (cppcheck doesn't seem to even find the syntax error in `if(1,1){}`) This commit causes such errors to be silently ignored, as they are not actionable.
