double StatisticsCV(const std::vector<double>& v)function gets vector of zeroes on system with low frequency timers inuser_counters_tabular_testtestBM_Counters_Tabular/repeats:2/threads:1_cvcase. Division result isnanand test fails due to regexp mismatch.Additionally, division by zero (even FP zero) is a UB in C++ and should be avoided.
