If a roundabout is in the middle of a route sometime the wrong exit is recommended.
I think it is because low priority ways outside the route_depth settings are not in the routing memory.
In navigation.c is a check which count only allowed ways in the routing memory.
While testing I found NULL pointer to the low priority ways, but it is to complicated for me.
The text for the sample is "leave the roundabout at the first exit"
