If there's undefined behavior (UB) somewhere in the test or the tested unit then the compiler could skip any checks and report success anyway. Not adding UB in the test framework and tests is the least we can do. Perhaps disabling link-time optimization would allow us to shield the unit tests from UB in the tested code, in the sense that the compiler would then not be able to skip checks. René
