Hi Jakob,
unfortunetaly, the self-compiled SUMO does not exhibit the problem. It
happens e.g. with v.1.4
(https://sumo.dlr.de/releases/1.4.0/sumo-win64-1.4.0.zip) and a dev
build from past November. I remember some similar issues with SSM device
recently where I was unable to further investigate. From a first look,
the referenced DLLs look fine when comparing for different builds on the
same computer. Any idea why?
Best regards
Mirko

I'd first try with some debug output for forward movement:
https://github.com/eclipse/sumo/blob/1267528511f2cfa3224884c2ec08fb5b5ef9cdbd/src/microsim/MSVehicle.cpp#L92-L95
Then select the vehicle in sumo-gui and check the resulting console
output (send it to sumo-dev or attach it to a ticket if it's too obscure).
Note, that the release build on windows does not write to stdout so
you either have to do this on linux or use the debug build.
My guess is that the behavior somehow results from lane-changing so
you may want to switch on that output as well:

Hi there,
have a look at the screenshot below to see what happened:
The leading yellow vehicle wants to change to go one lane to the
left, but instead it stops inside an intersection and creates a
big queue behind. The yellowish lane shows the edges of its route.
This error is very difficult to isolate (lots of custom things in
my simulation) and does happen only seldomly (at one position, for
a specific seed). What I already tried:
* record my traffic light downstream (controlled externally) and
reset it to the recorded signal program >> the yellow vehicle
does not stop
* record the simulation state short before the position shown in
the screenshot and load it back >> the yellow vehicle does not
stop
Maybe somebody (Jakob?) has an idea either what else can be done
to either get a working example or where to look: lane change
parameters, lane change model (state) debugging...
Best regards
Mirko
