UpdateVehiclePosHash assertation failure (0.3.5)

[toholio]

The dedicated server I've been running has crashed several times in the last day. Looking through the logs I see the following right before the server shuts down:

openttd: vehicle.c:316: UpdateVehiclePosHash: Assertion `idx != 0xffff' failed.

I can't see why this would only start happening now. Is there a setting or patch that makes this more likely? Is there something a player could do to cause this?

Are other servers experiencing this?

I can't explain it either, but in fact assertions shouldn't be a problem in release builds. They are only a way of showing the devs that something happened which shouldn't happen. In release builds they are supposed to be disabled. You have built this version you are running yourself, right? If so, please build it as a release, that way you won't get any assertion errors. Depending on the seriousness of the assertion, this might cause other problems. But often it doesn' t.

Yes.

If so, please build it as a release, that way you won't get any assertion errors.

'make DEDICATED=1 RELEASE=0.3.5' should be sufficient, right?

I'm not sure about that, Bjarni is our makefile man. Just to be sure it'd be good to set "DEBUG:=" (no value) in Makefile.config.
