  The C++11/14 standard offers a wealth of features aimed at helping
programmers write better code. Unfortunately, some of these features may cause
subtle programming faults, likely to go unnoticed during code reviews. In this
paper we propose four new mutation operators for C++11/14 based on common fault
patterns, which allow to verify whether a unit test suite is capable of testing
against such faults. We validate the relevance of the proposed mutation
operators by performing a case study on seven real-life software systems.
