I've been working on adding UBSan support to CMake (so that errors found by it can be uploaded to CDash for viewing). One problem is that the message is very generic. The patch here addes 'UndefinedBehaviorSanitizer' to the message so that they may be detected more easily. If something else is wanted (such as the '===' lines from ASan or TSan to cope with things like printing
