Reduced testcase:

  int m_xp, m_yp, m_xl, m_yl, a, b;
  bool m_multi_quants;
};

  int Length() const;
  Subband& operator()(void){return *(_M_start);}
  Subband *_M_start;
};
struct BandCodec
{
  BandCodec(int band_num);
  virtual void DoWorkDecode(void);
  virtual ~BandCodec ();
};
struct IntraDCBandCodec : public BandCodec
{
  IntraDCBandCodec(const SubbandList& band_list)
    : BandCodec(band_list.Length()) {}
};
void Decompress()
{
    SubbandList bands;
    bands().m_multi_quants = 0;
    new IntraDCBandCodec(bands);

Did you get a chance to see whether this test case still fails?
