Only some routes.

I start from one side to the other of the city (not too close to the outer highway ring, otherwise the routing goes on that ring and it works).

The routing fails.

Then I try other routes closer to the centre always looking for the routing failure and I'm able to get closer to some crosses in the center of the city that cannot be routed (trying even a simple route from one street to the next one fails).

These crosses have nothing wrong in OSM (as far as I know). And they are not always the same while the OSM database has changed during last weeks. So it seems to be some overflow/pointer problem in mkgmap/splitter that just brakes the routing info on those crosses.

Anyway I'm just recompiling the today's database with mkgmap 1563 and splitter 105, so we can have the exactly same data.

as I said:
