It comes from `die()`:

-- snip --
static NORETURN void die_builtin(const char *err, va_list params)
{
        /*
	 * We call this trace2 function first and expect it to va_copy 'params'
	 * before using it (because an 'ap' can only be walked once).
	 */
	trace2_cmd_error_va(err, params);

	vreportf("fatal: ", err, params);

	exit(128);
}
-- snap --

Thanks,
Dscho
