#491 closed defect (fixed)

stack-use-after-scope in xIBCEstimation()

I found the following with libasan:

in void InterSearch::xIBCEstimation() is the follwing code:

  if ((pu.cs->slice->getLmcsEnabledFlag() && m_pcReshape->getCTUFlag()))
    const CompArea &area = pu.blocks[COMPONENT_Y];
    CompArea    tmpArea(COMPONENT_Y, area.chromaFormat, Position(0, 0), area.size());
    PelBuf tmpOrgLuma = m_tmpStorageLCU.getBuf(tmpArea);
    pcPatternKey = (CPelBuf*)&tmpOrgLuma;

pcPatternKey is used later on, although tmpArea has been cleaned up by leaving the definition scope.
