SystemVerilog const definition issue manifested in quartus_map

To eliminate the issue, I moved the constant inside a function (still inside the package file) that I used to access individual elements in the seed constant. Instead of referring to the constant in my hdl, I referred to the function which returns the element of the constant array specified by the index input to the function.

So, I have something that works now, but if anyone has any insight into why the original code shown above doesn't work, it would be helpful. I am trying to understand if my coding (a) violated SystemVerilog spec -- I don't think so..., (b) is not supported in Quartus 11, or (c) hit a corner case in Quartus.

Thanks.
