CID: 10198
Checker: DIVIDE_BY_ZERO
Category: No category available
CWE definition: http://cwe.mitre.org/data/definitions/571.html
File: /tmp/buildd/dee-1.0.4/tests/test-benchmark.c
Function: run_benchmark()
Code snippet:
 86 {
 87 gdouble delta = bench->runs[i].elapsed - avg_runtime;
 88 std_dev += delta * delta;
 89 }
CID 10198 - DIVIDE_BY_ZERO
Division by expression "bench->n_runs" which may be zero has undefined behavior
 90 std_dev = sqrt (std_dev / bench->n_runs);
 91 coeff_of_var = (std_dev /avg_runtime) * 100;
 92
 93 /* This is not a very precise way of judging the quality,
 94 * but better than rigorous hand waving */
 95 if (coeff_of_var < 1.0)
