How-To-Repeat 
Compile the following source code with following command:
	
	gcc -Wunused -O -c t.c

Source code:
--------------cut start--------------
typedef enum {
    NO_oik, 
    PSC_oik, 
    JEE_oik, 
    SSC_oik, 
    DEC_oik
    } 
    jee;

jee j_oikvent_code;

main()
{

    exit(0);

    {
        unsigned int loop;

        for(loop=0; loop < 2; loop++)
            {
            }
    }
        switch(j_oikvent_code) {
        case  PSC_oik:

          break;
        case  JEE_oik:
          if(j_y_state == y_STATE_ACTIVE)
            {
            y_act_JEE_result(&sig, &y_meas_act_data);
            }
          break;
        case  SSC_oik:
          break;
        case  DEC_oik:
            break;

        }
