When the --verbose option is selected, the first value for each thread is
incorrectly reported as zero.
This is because when collecting the first value, the index into stat->values is
incremented from zero to one before storing the value. But when printing the
values, the first value printed is stat->values[0], which has been initialized
to zero.
