In my experience with porting linux kernel , or android code to different platform many time we do something wrong and in logcat we see some error like

if ( x < 0 )
{
    x = 0;
}
else if ( y < 0 )
{
    x = 3;
}
else    /* this else clause is required, even if the */
{       /* programmer expects this will never be reached */
        /* no change in value of x */
        printk(" \n [function or module name]: this should never happen \n");

        /* It is always good to mention function/module name with the 
           logs. If you end up with "this should never happen" message
           and the same message is used in many places in the software
           it will be hard to track/debug.
