#5868 assigned defect
Avoid alias elimination of individual elements of an array

Description
Certain operations involving arrays (e.g. passing them as inputs to functions) only work if their integrity is preserved. In some cases, the removeSimpleEquations algorithm in the backend eliminates some elements of arrays in favour of other scalar aliases, jeopardizing the correctness of those operations.
The removeSimpleEquations should be fixed to avoid eliminating individual components of arrays when doing alias elimination.

@Karim, do you think this could be actually fixed in 1.17.0? This could have some impact.
