2837	Wrong code generation for model	Adrian Pop	Lennart Ochel	"This pattern is not properly supported in the back-end or code generation:
{{{#!mo
model ArrayModel

   function lift
      input Real x;
      input Real y;
      output Real[1] z;
    algorithm
      z := {x};
    end lift;
    
    parameter Real x = 10;
    Real z[1];
equation
    z = lift(x, 0.0);
end ArrayModel;
}}}

We get:
{{{
ArrayModel_06inz.c: In function 'ArrayModel_eqFunction_1':
ArrayModel_06inz.c:71: error: incompatible types when assigning to type 'modelica_real' from type 'real_array_t'
}}}
and codegen looks like:
{{{
/*
 equation index: 1
 type: SIMPLE_ASSIGN
 z[1] = (ArrayModel.lift(x, 0.0) - z) ./ {1.0}
 */
void ArrayModel_eqFunction_1(DATA *data)
{
  const int equationIndexes[2] = {1,1};
  TRACE_PUSH
  real_array tmp0;
  real_array_create(&tmp0, ((modelica_real*)&($Pz)), 1, 1);
  $Pz$lB1$rB = div_alloc_real_array(sub_alloc_real_array(omc_ArrayModel_lift(threadData, $Px, 0.0), tmp0), _OMC_LIT0);
  TRACE_POP
}
}}}
Which seems rather wrong.

This kind of pattern is used in the PowerSystems library."	defect	closed	high	1.9.1	Backend	trunk	fixed		Willi Braun
