Cannot find route between points A-B-A

[boooch]

When I search route between points A-B-A it says Cannot find route between points
http://router.project-osrm.org/viaroute?output=json&geomformat=cmp&instructions=false&loc=55.8178,37.7434&loc=54.5133,36.2688&loc=55.8178,37.7434

But if i search separate between A-B and B-A it says Found route between points
A-B
http://router.project-osrm.org/viaroute?output=json&geomformat=cmp&instructions=false&loc=55.8178,37.7434&loc=54.5133,36.2688
B-A
http://router.project-osrm.org/viaroute?output=json&geomformat=cmp&instructions=false&loc=54.5133,36.2688&loc=55.8178,37.7434

is it a bug? of feature ? ;-)

Of course, a feature 😀

It's a bug that occurs when the via node is on a dead-end street with a barrier node in between. If you move it slightly, it works: http://osrm.at/5Ka

Documented bug is a feature.

Thanx for help.

Alright, after a debugging session that took more than a day, I have a lead on the root cause of the issue. Hope to push a fix until the end of the week.
