Hi,

My mistake, it seems the memory run-out occurs when creating
odeModel_t*:

This does work:

int main()
{

  int ctit;
  string modelFilename = "../../models/CC.xml";
  SBMLDocument_t *d;
  Model_t *m;

  d = readSBML(modelFilename.c_str());
  m = SBMLDocument_getModel(d);

  for(ctit = 0; ctit != 10000; ++ctit)
    {
      m = SBMLDocument_getModel(d); //DOES NOT EXHAUST!!
    }
}

but this segfaults after only 114 created instances of odeModels:

int main()
{

  int ctit;
  string modelFilename = "../../models/CC.xml";
  SBMLDocument_t *d;
  Model_t *m;

  d = readSBML(modelFilename.c_str());
  m = SBMLDocument_getModel(d);

  for(ctit = 0; ctit != 10000; ++ctit)
    {
      m = SBMLDocument_getModel(d); //DOES NOT EXHAUST!!
      odeModel_t* om = ODEModel_create(m); //SEGFAULT!!
    }
}

Is an odeModel structure that big, or is there a possible memleak ?
