Re: stack overflow error when using vector stl

I modified your code to get it to compile and it ran fine.
The one flaw I noticed was that you are initializing your vectors with:
     vector< vector <Tissue*> > tissueArray(cRows);
and later,
     vector<Tissue*> tRow(cCols);
I don't think you want to do that, since you're using push_back().
Below, I leave off the ctor argument, and use vector::reserve() to set the
initial capacity.

#include <iostream>
#include <vector>

using namespace std;

enum TissueType { Fibre, Vessel };

enum TissueStimulus { Absent, Present };

enum TissueState { Inactive, Active };

const double Fpo2 = 0.0;

struct Tissue {
  TissueType type; // Fibre or Vessel
  TissueStimulus stimulus;
  TissueState state;
  double tpo2;
  double po2;
  double deficit;
  double demand;
  double x;
  double y;
  double v;
  double u;
  double Iext;
}; // Tissue

Tissue* createFibre() {
  Tissue* tissue;
  tissue = new (Tissue);
  tissue->type = Fibre;
  tissue->po2 = Fpo2;
  tissue->state = Inactive;
  tissue->stimulus = Absent;
  tissue->deficit = tissue->demand = 0.0;
  tissue->x = tissue->y = tissue->Iext = tissue->v = tissue->u
      = tissue->tpo2= 0.0;
  return (tissue);
} // createFibre

Tissue* createVessel() {
  Tissue* tissue;
  tissue = new (Tissue);
  tissue->type = Vessel;
  tissue->po2 = Fpo2;
  tissue->state = Inactive;
  tissue->stimulus = Absent;
  tissue->deficit = tissue->demand = 0.0;
  tissue->x = tissue->y = tissue->Iext = tissue->v = tissue->u
      = tissue->tpo2= 0.0;
  return (tissue);
} // createVessel

int main() {
  const int cRows = 300;
  const int cCols = 300;
  TissueType type = Vessel;
  vector < vector < Tissue* > > tissueArray;
  tissueArray.reserve(cRows);
  for (int i = 0; i < cRows; i++) {
    //creating a row of tissue cells
    vector <Tissue*> trow;
    trow.reserve(cCols);
    for (int j=0; j<cCols; j++) {
      if (type == Fibre) {
        trow.push_back(createFibre());
        type = Vessel;
      }
      else {
        trow.push_back(createVessel());
        type = Fibre;
      }
    }
    tissueArray.push_back(trow);
  }
  cout << "Everything is fine here." << endl;
  return 0;
} // main
