Description

The INACTIVE (pass rate) column displays the wrong result when the total number of assertions is large:

$ cat t.cpp && make t && ./t
#include <driver.h>

int test (int, char**) {
for (int i = 0; i != 77810809; ++i)
rw_assert (1, 0, 0, "");
return 0;
}

int main () {
rw_test (0, 0, 0, 0, 0, test, 0, 0);
}
