I have this problem with SIGFPE...


double DistanceBetweenPoints(strPOINT *Pt1, strPOINT *Pt2)
{
  double Dist;

  Dist = pow(fixtof(Pt1->X - Pt2->X), 2)+
         pow(fixtof(Pt1->X - Pt2->X), 2)+
         pow(fixtof(Pt1->X - Pt2->X), 2);
  Dist = sqrt(Dist);
  printf("Dist = %f\n", Dist);  <----- program crashes here with SIGFPE
}

traceback:
_doprnt+3548
_doprnt+1574
printf+20
DistanceBetweenPoints

and I #included math.h

Why would SIGFPE appear in a mere printf ?
What causes SIGFPE anyway ?
If I remove the printf, I get SIGFPE at "if (Dist1[I] <= Dist2[J])"
  (Dist1[6] and Dist2[6] are float)
