Client crash - probably due to private car bug

[Matthew]

Steps to reproduce

0. Possibly on Linux only - will try Windows later
1. Run the current official Simutrans-Extended executable #d16d1d7
2. Load this Bridgewater-Brunel savegame (but this bug was originally found by connecting the client to B-B, where it occurred a couple of times)
3. Wait a few minutes.

Expected behaviour

Game is playable.

Actual behaviour

Client soft crashes with the following error message:

FATAL ERROR: vector_tpl<T>::[] - 18ordered_vector_tplI5koordjE: index out of bounds: 7735 not in 0..7734
Aborting program execution ...

It's probably irrelevant, since deleting this convoy does not prevent the crash.

Observations

Shortly afterwards, the listserver reported that the server was running and another client was connected, which suggests that some other players were not affected. Reports from other players would be helpful.

Steps to reproduce

0. Possibly on Linux only - will try Windows later
1. Run the current official Simutrans-Extended executable #d16d1d7
2. Load this Bridgewater-Brunel savegame (but this bug was originally found by connecting the client to B-B, where it occurred a couple of times)

Expected behaviour

Game is playable.

Actual behaviour

Client soft crashes with the following error message:

Observations

Shortly afterwards, the listserver reported that the server was running and another client was connected, which suggests that some other players were not affected. Reports from other players would be helpful.

Thank you for your report. I believe that I have fixed this. I should be grateful if you could re-test with the next nightly build.

[Matthew]

This bug appears to be fixed with this morning's build #f1c0de6. Thank you, James! Private cars & carriages makes Sim-Ex a better game as no one is safe from competition.
