The bug occurred both when starting a new game and loading any of my old save games. Below are some of the tests I ran on a new game: Server Settings: Default Starting units: Explorer, 2 Workers, 2 Settlers. Test Scenario 1 Moved Explorer, moved settlers, set worker 1 to build road, worker 2 to build irrigation.

I'm starting to suspect that it might be a compiler bug (we've had problems before due to code not working when compiled with gcc 4.x optimizations). What version of gcc are you using, and do you know if the freeciv binary you are using was compiled with -O2 (or more)? If you have some time it would help my debugging too if you could confirm whether the 2.1.8 sources in svn://svn.gna.org/svn/freeciv/branches/S2_1 when compiled with with or without --enable-debug and with or without optimizations (-O0 that's big oh, zero) or with an earlier gcc (e.g. 3.x). --- ボリボリ食べるな！ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

[Freeciv-Dev] (PR#40610) auto_arrange_workers: Assertion `cmr.found_a_valid' failed.
URL: http://bugs.freeciv.org/Ticket/Display.html?id=40610 This was reported on the forums: http://forum.freeciv.org/viewtopic.php?t=5730 Server fails to autoarrange workers triggering the assertion in the subject line. The program version is 2.1.8, a fedora package. Server log also has: 3: Warning: calloc with size 0 at line 576 of cm.c 3: Warning: calloc with size 0 at line 577 of cm.c which indicates that ntypes=0 is passed to the function init_partial_solution(). I assume this was never expected by the author of that function, so the server must have gotten into an inconsistent state some time before that point (missing city workers or wrong city size?). I could just make the cm functions more robust (i.e. better checking of arguments) and turn the assertion in auto_arrange_workers() into an if-statement, but I will investigate some more and hopefully find the real cause of the bug. :( --- クリスマスには石炭の塊だけが欲しい。 ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
