strange routing decisions

Description

Latest builds of Gosmore seem to take some strange routing decisions. The three cases I have seen so far all occur when a roundabout is involved.

Attached are screenshots of Gosmore routing decisions together with a text file showing the route as a www.yournavigation.org link (whilst I appreciate yournavigation doesn't use the current Gosmore version, providing these links seemed to me the best way of summarising the route I put into Gosmore).

I cannot update http://www.yournavigation.org with a newer Gosmore version because of this ticket: http://trac.openstreetmap.org/ticket/2386

Please note my ticket 2423 did not refer to the fact that Yournavigation was out of date or making strange routing decisions. The only reason I referred to Yournavigation was to summarise the routes I was referring to as being incorrect in Gosmore.

Ok, I understand now. Btw, shouldn't those roundabout have a oneway tag?

Not according to http://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout which states "there is no need to tag them as oneway"

Then Gosmore needs to learn how to use the way direction as indication on how to take a roundabout. Because, when I reverse the route of one of your examples then Gosmore consistently takes the inner corner of a roundabout. It doesn't show this behavior if a roundabout has a oneway tag (which is why I asked).
