Livestatus and CMC can use one of two regex engines: Either then one from the C++11 standard library or the one from the RE2 library. Normal builds ship the latter, only a manually built Livestatus should ever use the former. Nevertheless, both should work, but the C++11 variant had a quoting bug, resulting in incorrect matching. This has been fixed.
