Hi Gerd,
Analyzing and comparing the syntax of your test osm file with my test one, I found an error in my syntax. The roundabout where I get the unexpected behavior, the first and the last nodes aren't the same. I mean, the wrong syntax was the one below:
<node id="3" lat="-20.4545397" lon="-40.4486877" visible="true" version="1"/>
<node id="15" lat="-20.4566083" lon="-40.4487237" visible="true" version="1"/>

Hi Alexandandre,
I tried to reproduce the problem using the attached input file. Routing works for both cases.
So there is probably more to it. If you can reproduce the problem, please let me know how.

Hi Alexandre,
seems that you have test data. Please post a link to it.

Hi guys,
We note in our group a strange behavior in some roundabounts that are complete loops. Investigating, we discovered that when the starting and ending points of a roundabout coincides with a routable node, we are able to route through this roundabout. However, if the starting and ending points of a roundabout don't match a rountable node, we have problem to route through this roundabout.
The example bellow shows this clearly when trying to create a route em Mapsource from point A to B:

Thank you for your time.
