corrupted double-linked list on on destroying map

[jamespetts]

Thank you for your report. I am having some trouble reproducing this (albeit on Windows). Can you be more specific about the steps necessary to reproduce? In particular, can you upload a saved game the closing of which reliably leads to this issue? Thank you.

Hi,
Thanks for the prompt response.

It happens with the default savegame that is loaded on the first start. So I can't load anything else.
In the meantime I tried changing the DEBUG variable in the Makefile and then recompiling, and after that, I can't reproduce it any more with the current master. It's still happening with the nightly built at 2017-06-26 05:10, though.

I thought it had something to do with the leftovers form the last version, but it's the same even after removing ~/simutrans and ~/.simutrans-ex directories.

[jamespetts]

Thank you for that. May I ask to what you changed the DEBUG variable in the makefile? This might well provide a clue to the problem. Also, I note that your original post referred to a doubly linked list; may I ask how you identify it as such? Simutrans does not use doubly linked lists (although does use singly linked lists in some places); James. PS: I am about to go away for a day or so, so will not be able to deal with this further in any detail before Wednesday.

I set DEBUG=1, then 3, and then removed it.
make clean between changes
Also, I compiled it using make -j9, if it makes any difference.

The "corrupted double linked list" is a glibc message.

*** Error in `/media/multimedia/games/simutrans/extended-120/simutrans/simutrans': corrupted double-linked list: 0x00000000219580e0 ***

[jamespetts]

Can I ask you to confirm (1) which was the debug setting (i.e., DEBUG=1, DEBUG=3 or no DEBUG defined at all) that did not crash; and (2) whether the crash can be reproduced using the pre-compiled nightly binary from the Bridgewater-Brunel server? Thank you; James.

While testing for reproduction of the bug I stumbled upon the steps. The nightly/master or DEBUG variable have no effect.

If the ~/simutrans directory (or its contents) was missing when launching the executable, this error will always happen.

[jamespetts]

Thank you for confirming that. Does it ever occur if that directory is not missing?  Sent from my Samsung Galaxy smartphone. -------- Original message --------From: Mak Krnic <[email protected]> Date: 26/06/2017 11:09 (GMT+00:00) To: jamespetts/simutrans-extended <[email protected]> Cc: jamespetts <[email protected]>, Comment <[email protected]> Subject: Re: [jamespetts/simutrans-extended] corrupted double-linked list on on destroying map (#53) While testing for reproduction of the bug I stumbled upon the steps.

No, I haven't been able reproduce it and I have run and quit the game quite a few times.

[jamespetts]

Splendid, thank you for confirming. May I ask - did the game not automatically create this directory when it was first run? Was it, perhaps, not run with a user account with permission to create this directory? James. Sent from a tablet computer.

Yes, the game does create it, with accompanying contents, and subsequent runs are working normally.
