Index out of bounds for array returned by built-in function

[Andreas Heuermann]

I have a model that simulates with the old frontend but fails to simulate with the new frontend.

setCommandLineOptions("-d=newInst");
loadString("
model mwe 
  parameter Integer dim=4;
  Real vectorA[1,dim];
  Real vectorB[1,dim];
equation
  vectorA = {{1,2,3,4}};
  vectorB = tanh(vectorA) .* ones(1,dim);
end mwe;
"); getErrorString();
simulate(mwe); getErrorString();

true

record SimulationResult
    resultFile = "",
    simulationOptions = "startTime = 0.0, stopTime = 1.0, numberOfIntervals = 500, tolerance = 1e-06, method = 'dassl', fileNamePrefix = 'mwe', options = '', outputFormat = 'mat', variableFilter = '.*', cflags = '', simflags = ''",
    messages = "Simulation execution failed for model: mwe

Not sure if this is a frontend, backend or runtime problem. We'll can push it around a bit.
