Segmentation Fault from libgurobi100.so

Hello,

I recently cloned a C++ project that uses the Gurobi solver. I just booted my computer with Ubuntu, so I installed Gurobi and downloaded my academic license.

This code is supposed to work correctly, but an error persists when I run :

0x00007ffff59786db in PRIVATE00000000008d2227 () from /home/timothy/opt/gurobi1003/linux64/lib/libgurobi100.so

Here's some additional information: 

I'm using a CMake project and here are the values I've specified for the variables:

GUROBI_CXX_LIBRARY: /home/timothy/opt/gurobi1003/linux64/lib/libgurobi_c++.a
GUROBI_INCLUDE_DIRS: /home/timothy/opt/gurobi1003/linux64/include/
GUROBI_LIBRARY: /home/timothy/opt/gurobi1003/linux64/lib/libgurobi100.so

I'm just starting out with CMake and it's possible I'll make mistakes.

Here is the portion of code that is causing problems:

GRBenv* env;
      GRBmodel *model;

      int savedStdout = dup(1);
      close(1);
      int newStdout = open("/dev/null", O_WRONLY);
      assert(newStdout == 1);

      // Create the Gurobi model.

      GRBloadenv(&env, "");
      GRBnewmodel(env, &model, nullptr, 0, nullptr, nullptr, nullptr, nullptr, nullptr);

      // Restore stdout.

      close(newStdout);
      newStdout = dup(savedStdout);
      assert(newStdout == 1);
      close(savedStdout);

      if (_data.verbosity < 2)
         GRBsetintparam(GRBgetenv(model), "outputflag", 0);
      GRBsetintparam(GRBgetenv(model), "threads", 1);
      GRBsetintattr(model, "modelsense", GRB_MINIMIZE);

      // Add the variables.

      auto obj = new double[_data.maximalRectangles.size()];
      auto lb = new double[_data.maximalRectangles.size()];
      auto ub = new double[_data.maximalRectangles.size()];
      auto vtype = new char[_data.maximalRectangles.size()];
      for (std::size_t i = 0; i < _data.maximalRectangles.size(); ++i)
      {
         obj[i] = 1.0;
         lb[i] = 0.0;
         ub[i] = _refined ? 2.0 : 1.0;
         vtype[i] = GRB_INTEGER;
      }

      GRBaddvars(model, _data.maximalRectangles.size(), 0, nullptr, nullptr, nullptr, obj, lb, ub, vtype, nullptr);

      delete[] obj;
      delete[] lb;
      delete[] ub;
      delete[] vtype;

      // Actually add the variables.

      GRBupdatemodel(model);

      std::vector<int> indices;
      std::vector<double> coefficients;
      indices.reserve(_data.maximalRectangles.size());
      coefficients.reserve(_data.maximalRectangles.size());
      for (std::size_t s = 0; s < _data.numNonzeros(); ++s)
      {
         indices.clear();
         for (std::size_t r = 0; r != _data.maximalRectangles.size(); ++r)
         {
            auto rectangle = _data.maximalRectangles[r];
            if (rectangle->nonzeros[s])
               indices.push_back(r);
         }
         coefficients.clear();
         coefficients.resize(indices.size(), 1.0);
         GRBaddconstr(model, indices.size(), &indices[0], &coefficients[0], '>', 1.0, nullptr);
      }
   
      if (_refined)
      {
         for (std::size_t i = 0; i < _data.numFoolingPairs(); ++i)
         {
            const FoolingPair& fp = _data.foolingPairs[i];
            indices.clear();
            for (std::size_t r = 0; r != _data.maximalRectangles.size(); ++r)
            {
               auto rectangle = _data.maximalRectangles[r];
               if (rectangle->nonzeros[fp.nonzero1] || rectangle->nonzeros[fp.nonzero2])
                  indices.push_back(r);
            }
            coefficients.clear();
            coefficients.resize(indices.size(), 1.0);
            GRBaddconstr(model, indices.size(), &indices[0], &coefficients[0], '>', 2.0, nullptr);
         }
      }

      if (_data.verbosity > 1)
      {
         std::cerr << "\n  Initialized IP with " << _data.maximalRectangles.size() << " variables and "
            << (_data.numNonzeros() + (_refined ? _data.numFoolingPairs() : 0)) << " constraints." << std::endl;
      }

      GRBupdatemodel(model);

      GRBoptimize(model);

Thank you in advance for your help,
