I can confirm this beaviour, and I have a location in Italy where it happens always, it could be reproduced easily at least on my smartphone.
Basically, in this area:http://world.waze.com/cartouche/?zoom=1 ... FFFFFFTTTT
moving from A1 to A13 using A1-A14 junction my waze always crashes, more or less in the same place. This happens at least from 184.108.40.206.
I've yet to figure out why or what is on the map that causes this.
Note that this is not the only place where it happens, but at least in all cases I've seen, it happens on specific places on the map.
Galaxy S, 2.3.3 and 2.3.4, no difference.
