CC Mode 5.28 (C++); contained expression ends prematurely

CC Mode 5.28 (C++); contained expression ends prematurely

[Neal D. Becker]

I can't indent this code on line 15 or 16.  It just beeps saying Containing expression ends prematurely

Here is the code:

#ifndef iPowerNorm_H
#define iPowerNorm_H

#include "Complex.H"
#include "FixedUtil.H"
#include "Mag.H"

class iPowerNorm {
public:
  iPowerNorm (int _targetVoltage, int _shift1, int _shift2, int _init) :
    targetVoltage (_targetVoltage),
    shift1 (_shift1),
    shift2 (_shift2),
    sum (_init << _shift1),
voltage (_init),
adj ((_targetVoltage << shift2)/_init)
  {}

  ComplexI Compute (ComplexI in) {
    ComplexI out = RoundDown (in * adj, shift2);
    sum = sum - (sum >> shift1) + Mag (out);
    voltage = sum >> shift1;
    adj = (targetVoltage << shift2) / voltage;
    return out;
  }
  
  int GetSum() const { return sum; }

  int GetAdj() const { return adj; }

  int GetVoltage() const { return voltage; }

private:
  int targetVoltage;
  int shift1;
  int shift2;
  int sum;
  int adj;
  int voltage;
};

#endif
