[Bug c++/37143] [4.4 Regression] ICE in VRP with the auto-vectorizer

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2008-08-18 03:33 -------
It is definitely related to that other PR.  Here is a reduced testcase:
void
f(int NumberOfSideSets, int *ssNumDFperSide, float *ssDF)
{
  int i;
  float *newssDF = __null;
  int *newssNumDF = new int [NumberOfSideSets];
  int numNewDF = 0;
  int ii=0;
  for (i=0;  i<NumberOfSideSets;  i++)  
    numNewDF += newssNumDF[i];
  if (numNewDF > 0)
    newssDF = new float [numNewDF];
  int nextDF = 0;
  int ndf = ssNumDFperSide[ii];
  for (i=0;  i<ndf; i++)
    newssDF[nextDF++] = ssDF[i];
}
