Jens,

 I commented the line 229 where the wire duplicates the parameter. Somehow
iverilog ignored that error in the previous versions.

But the thing is that we use a Linux-system...

Yes, consuming much memory by Xilinx tools is a normal thing. You could try
installing ModelSim, but I'm not sure the evaluation version supports mixed
projects.
So, with Icarus and GTKWave currently you can only check how 359's modules
(like i2c & memory controller) work.
