Hello everyone.

I've got a modelica package I'm trying to get to work. To replicate an error, I'm trying a reduced model. I haven't been able to replicate the problem, but I'm running into other issues. Here's my reduced model:

model mod2
  constant Integer n=3;
  output Real Z[n, n];
  Real V[n], I[n];
  Integer i=1, k=1;
algorithm
  for i in 1:n loop
    for k in 1:n loop
      Z[i,k] := i * k;
    end for;
  end for;
equation
  I = fill(1.0,n);
  V = Z * I;
end mod2;

Here are the issues:

(*) I needed to add the "=1" to i and k to make the equations and variables balance (17 of each according to omc). I'm not sure why. The model looks balanced without that.

(*) The model flattens, but it fails during simulation. Here are the errors:

mod2.cpp: In function `int functionDAE_output()':
mod2.cpp:663: error: expected initializer before '->' token
mod2.cpp:667: error: expected initializer before '->' token
mod2.cpp: In function `int function_updateDependents()':
mod2.cpp:837: error: expected initializer before '->' token
mod2.cpp:841: error: expected initializer before '->' token
mod2.cpp: In function `int function_updateDepend(int&)':
mod2.cpp:882: error: expected initializer before '->' token
mod2.cpp:886: error: expected initializer before '->' token
mingw32-make: *** [mod2] Error 1

The code generated looks like this:

663    for(modelica_integer $Pi = 1; in_range_integer($Pi, tmp6, tmp8); $Pi += tmp7) {
664      tmp5 = get_memory_state();
665      tmp2 = 1; tmp3 = (1); tmp4 = 3;
666      {
667        for(modelica_integer $Pk = 1; in_range_integer($Pk, tmp2, tmp4); $Pk += tmp3) {
668          tmp1 = get_memory_state();

I'm wondering if I'm somehow getting the wrong compiler version or something.

If I change the algorithm part to the following, it simulates correctly. Also, if I move the algorithm part to a separate function and call it from the model, it simulates correctly.

  Z := {{1,2,3},{4,5,6},{7,8,9}};

I'm on windows XP. These results are on a fairly recently downloaded daily (OpenModelica-revision-6338.msi).
