I tried max-nodes=200000 (although I don't I understand why should I use 
so low number for an area where I'm using max-nodes=1900000/1600000 
without problems using different input files), but still the same 
problem. Any attempt to use lower max-nodes resulted in the following error:
Splitting nodes into areas containing a maximum of 150.000 nodes each...

         ...

Finally I found the origin of the problem removing parameters from the 
command line one by one and the guilty one was  --area-name="Península 
Ibérica", so it seems that accented characters in area-name break the map.
