[kovarex] [0.17.31] Crash after train finishes a schedule composed of multiple temporary stops with no wait conditions

[ERJHolton]

Attached: Save file and log.

Mods: Some, but none that should affect train behaviour.

Description: When a train reaches the end of a schedule that consists solely of temporary stops that have all had their wait conditions removed, the game crashes.

Reproduction (using attached save file):
* Place a locomotive on the nearby roundabout.
* Open the schedule for the locomotive.
* Add 10 - 12 temporary stops within the circle of the roundabout, so it can get up to full speed before the end of the list.
* Delete all of the wait conditions on the temporary stops.
* Add fuel to the locomotive to set it going.
* Observe the schedule as the locomotive travels through the list.
* The game consistently crashes for me when it reaches the end of the list.

Situations where the game does not crash:
* If the last temporary stop on the list has a wait condition.
* If the last stop is a regular train station.

I tried to reproduce the crash, but I couldn't. I also don't see any crashlogs of this in the newest versions, so I assume, that it was fixed. Let me know if you can still reproduce it in the latest version.

Just tried again, and it still crashes.

Attached is a 7z file with log, dump, and a save file with the following slight updates:

* All mods removed
* Train already on the roundabout and set up with a schedule that'll crash the game reliably for me, just needs fuel.

Edit: you may have a couple of extra crash reports on this now. I've tried the save / schedule on two different computers and the crash was reproducible on them.

Thanks for the report and for the reproducer. It is now fixed for 0.17.40 (as 39 is already in the release process)
