I've narrowed down when it happens and managed to save the game about 10 secs before the crash. On my system it can be reliably repeated by simply loading the saved game and waiting! System is a reasonably up-to-date (a few days since last update) Arch Linux 32 bit and, this morning, I built widelands-bzr from the repository so I assume I'm running the latest version ? I've run the game from the command line and saved the output - Quite a few warnings but no errors I can see. What should I do next?? Top Quote

If you use the oneliner, all output will be redirected there but only last 20-50 lines of that file is relevant (is backtrace)..... should be recognizable for your... Top Quote

Since there are no line number, I expect that this was run with a release build. The savegame would still help, can you attach it to a bug on Launchpad? https://bugs.launchpad.net/widelands/ Thread 1 "widelands" received signal SIGSEGV, Segmentation fault. 0x006c6bd3 in Widelands::PartiallyFinishedBuilding::request_builder_callback(Widelands::Game&, Widelands::Re quest&, unsigned char, Widelands::Worker, Widelands::PlayerImmovable&) () #0 0x006c6bd3 in Widelands::PartiallyFinishedBuilding::request_builder_callback(Widelands::Game&, Widelands ::Request&, unsigned char, Widelands::Worker, Widelands::PlayerImmovable&) () #1 0x006d79c7 in Widelands::Ship::ship_update_idle(Widelands::Game&, Widelands::Bob::State&) () #2 0x006d8879 in Widelands::Ship::ship_update(Widelands::Game&, Widelands::Bob::State&) () #3 0x00694874 in Widelands::Bob::do_act(Widelands::Game&) () #4 0x006a7d75 in Widelands::CmdAct::execute(Widelands::Game&) () #5 0x00735be5 in Widelands::CmdQueue::run_queue(int, unsigned int&) () #6 0x0066247c in Widelands::Game::think() () #7 0x0081c3ea in InteractiveBase::think() () #8 0x0082a552 in InteractivePlayer::think() () #9 0x007b5f65 in UI::Panel::do_think() () #10 0x007b6f75 in UI::Panel::do_run() () #11 0x006676d3 in Widelands::Game::run(UI::ProgressWindow*, Widelands::Game::StartGameType, std::__cxx11::ba sic_string<char, std::char_traits<char>, std::allocator<charconst&, bool, std::__cxx11::basic_string<cha r, std::char_traits<char>, std::allocator<charconst&) () #12 0x00669ecc in Widelands::Game::run_load_game(std::__cxx11::basic_string<char, std::char_traits<char>, st d::allocator<charconst&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> const&) () #13 0x005b3c4f in WLApplication::load_game() () #14 0x005b538a in WLApplication::mainmenu_singleplayer() () #15 0x005b582e in WLApplication::mainmenu() () #16 0x005b5eab in WLApplication::run() () #17 0x0057412b in main () Busy indexing nil values Top Quote
