I have the following structs below.

static PinDelayPtr unspecifiedPipoDelayModel(new PinDelay());
#define DELAY_VALUE_NOT_GIVEN -7654321.0
typedef boost::shared_ptr<struct PinDelay> PinDelayPtr

struct DelayTime {
  double rise;
  double fall;
  DelayTime();
  DelayTime(const double r, const double f);
};

struct PinDelay {
  DelayTime block;
  DelayTime drive;
  double load;
  double maxload;
  DelayTime usertime;
  PinDelay();
  PinDelay::PinDelay(const double pload, const double pmaxload,
                     const double brise, const double frise,
                     const double bfall, const double ffall,
                     const double urise, const double ufall);
};

struct DelayWireLoadTable {
  double slope;
  unsigned int npinset;
  std::vector<double> pins;

// 'npinset' isn't used in the code you showed. Either remove it, or init
it.
DelayWireLoadTable() : slope(0.0), npinset(0){}
// or, see below...

};

struct DelayCircuitImpl {
  DelayTime defarr;
  DelayTime defreq;
  DelayWireLoadTable wltable;
  PinDelayPtr pipomodel;
};

My constructors looks like the following:

DelayTime::DelayTime()
  : rise(DELAY_VALUE_NOT_GIVEN), fall
          (DELAY_VALUE_NOT_GIVEN) {}

PinDelay::PinDelay()
  : load(DELAY_VALUE_NOT_GIVEN), maxload
           (DELAY_VALUE_NOT_GIVEN) {}

DelayCircuit::DelayCircuit()
  : dc(new DelayCircuitImpl()) {
  dc->wltable.slope = DELAY_VALUE_NOT_GIVEN;
  dc->pipomodel = PinDelayPtr(new
              PinDelay(*unspecifiedPipoDelayModel));

// OR here, if you don't want a Ctor (for POD struct):
dc->wltable.npinset = 0;

}
