#2230 closed defect (fixed)
model does not build - a discrete initialization generation bug ?

Description
Attached model does not build/simulate.
Build error (1 sample):
<<<
Dilution.c: In function 'eqFunction_83':
Dilution.c:1310: error: incompatible types when assigning to type 'modelica_real' from type 'real_array'
The problem bubbles also into C# generation, so the problem is somewhere in the SimCode or backend (??).
The attempted generated equations are from functionInitialEquations(), where seemingly unnecessary assignments of values to pre-values are generated.
The values are already set by the runtime, so the assignments are overshooting.
They are also using inappropriate ASUBs (with temporary arrays creation) instead direct crefs.
I'd recommend to filter them out completely to reduce bloating the generated code.

seem to be connected to #2217.
My guess is that the generation of pre variables while the symbolic initialization is wrong, but it's just a guess.

after fix, it should be able to simulate till stopTime=50
