possible wrong array size in Modelica.Mechanics.MultiBody.Visualizers.Colors.ColorMaps.jet

We had problems with the function

Modelica.Mechanics.MultiBody.Visualizers.Colors.ColorMaps.jet 

which is why I worked out the dimensions of all variables:

size(v1) = if (a<=2) then 1 else if (a <= 4) then 2 else floor(a/2);
size(v2) = a
size(v3) = a
size(v4) = floor(a/2)

The right hand side of cm has always 3 columns and the numbers of rows equals

size(cm_rhs,1) = size(v1) + size(v2) + size(v2) + size(v3) + size(v4) 
# size(v1) + 3*a + size(v4)

However, cm is defined as

Real cm[integer(a)*4,3];

which only matches the right hand side if a is an even number.
If we chose n_colors = 60, then we had a = 15 and size(cm,1) = 60 conflicting with size(cm_rhs,1) = 58.
