Examples of errors detected by the V519 diagnostic

V519. The 'x' variable is assigned values twice successively. Perhaps this is a mistake.


Crystal Space 3D SDK

V519 The 'sampleDistanceReal' object is assigned values twice successively. Perhaps this is a mistake. plgsimpleformer simpleformer.cpp 642


csVector3 sampleDistanceReal;

void csSimpleSampler::CachePositions ()
{
  ....
  // Compute distance between sample points
  sampleDistanceReal = (resx == 1) ? 0 :
    (maxCorner.x-minCorner.x)/(float)(resx-1);
  sampleDistanceReal = (resz == 1) ? 0 :
    (maxCorner.z-minCorner.z)/(float)(resz-1);
  ....
}

Most likely this is what should be written here: sampleDistanceReal.x = ...; sampleDistanceReal.z = ...;


Ultimate TCP/IP

V519 The 'prev' object is assigned values twice successively. Perhaps this is a mistake. UTHistory uh_ctrl.cpp 787


int CUH_Control::SetHistoryLength(int len){

  m_yMin = 32;
  m_nDelaySide = 0;
}

  r_shadows = ri.Cvar_Get( "cg_shadows", "1", 0 );
  ....
}

{
  ....
  k = nCoef-1;
  k = nCoef;
  ....
}

IPP Samples

V519 The '* tmpPtr' object is assigned values twice successively. Perhaps this is a mistake. aac_dec als_dec_api.c 928


AACStatus alsdecGetFrame(....)
{
  ....
  for (i = 0; i < num; i++) {
    ....
    *tmpPtr = (Ipp32s)((tmp << 24) + ((tmp & 0xff00) << 8) +
                      ((tmp >> 8) & 0xff00) + (tmp >> 24));
    *tmpPtr = *srcPrt;
    ....
  }

  ....
  saveXMask    = xMap->maskROI;

  saveYMask    = yMap->maskROI;
  saveYMask    = NULL;

{
  ....
  mNumOfFrames = par->NumOfFrames;
  mNumOfFrames = -1;
  ....
}

ifstream &operator>>(ifstream &ifs, vec &v)
{
  ....
  flag = true;

Strange code. The 'flag' variable is not used further at all.

{
  ....
  t=x1; x1=x2; x2=t;
