--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
### const unsigned long int f0 = (8UL*10^6) / (1000*256UL);
### // timer = ((31.2500 * 3600000UL) / ((unsigned long) desired_ml_per_h *
(unsigned long) syringe_step_per_ml));
### timer = ((f0 * 3600000UL)
Are you sure this does not overflow unsigned long to get 0?
