535	Unknown crash with DifEq	César Pérez Álvarez	Víctor de Buen Remiro	"When we compile this code:

-----------------------------------------------------------------
Set RandNoise(Date ini, Date end, TimeSet dating)
{
  Serie residuals = SubSer(Gaussian(0, 0.10, dating), ini, end);
  Polyn ma  = (1-0.6*B)*(1-0.5*B^7);
  Polyn ar  = (1-0.4*B);
  Polyn dif = (1-B)*(1-B^7)*(1-B^365); 

  Date iniRes = Succ(ini, dating, -Degree(ma));  
  Date endRes = Succ(ini, dating, -1);
  Serie iniResiduals = SubSer(Gaussian(0, 0.10, dating), iniRes, endRes);
  Serie noise = DifEq(ma/(dif*ar), iniResiduals<<residuals,8);
  SetOfSerie(ini, residuals)
};

Set test = RandNoise(y2000m01d01, y2007m01d01, Diario);
-----------------------------------------------------------------

TOL crashes. Its obvious that we have an eror in ""SetOfSerie(ini, residuals)"" because ""ini"" is a ""Date"" when it must be a ""Serie"" but TOL never must crash.

If we try with this another code:

-----------------------------------------------------------------
Set RandNoise(Date ini, Date end, TimeSet dating)
{
  Serie residuals = SubSer(Gaussian(0, 0.10, dating), ini, end);
  Polyn ma  = (1-0.6*B)*(1-0.5*B^7);
  Polyn ar  = (1-0.4*B);
  Polyn dif = (1-B)*(1-B^7)*(1-B^365); 

  Date iniRes = Succ(ini, dating, -Degree(ma));  
  Date endRes = Succ(ini, dating, -1);
  Serie iniResiduals = SubSer(Gaussian(0, 0.10, dating), iniRes, endRes);
//  Serie noise = DifEq(ma/(dif*ar), iniResiduals<<residuals,8);
  SetOfSerie(ini, residuals)
};

Set test = RandNoise(y2000m01d01, y2007m01d01, Diario);
-----------------------------------------------------------------

TOL does not crash, and a correct warning is advise us of our error.

I can not isolate much more the error, sorry."	defect	closed	high		Various	1.1.6	critical	fixed
