Please attach a save from a turn or two before this happens. It is very unlikely that the specific steps to reproduce are playing a newly started game with any settings for exactly 77 turns.

What is displayed on the options window Directories tab? Is that directory writable by the FreeOrion binaries and the user you're running the game as?

The directory is writable.

I did upload a saved game previously -- or thought I did. It just happened to me again at turn 54 in a new game.
Directories look fine and have files written to them.

I have attached log files and save games from a couple of turns before both incidents.

I have attached log files and save games from a couple of turns before both incidents.

Not that I can see... Yor comment just has text for the local path where some files are located, but no file attachments.

You might need to zip a .sav file for it to attach, but .log files attach OK for me.

Did these come through? Copy and paste wasn't working, I guess. This is Drag & Drop.

I believe I am getting the same bug: I can play for a while, but eventually the server segfaults, which causes the client to give a message saying the server connection has been lost.

Here's a save right before the crash - all I have to do is advance to the next turn.

And the gdb traceback for freeoriond when the crash happens:

Where did you find that? I would go over my logs looking if I knew where to look. I'm experienced in general, but compilers and such are something I haven't used much.

@SpikyCaterpillar

To find the process ID, in a terminal:

ps axuw|grep freeoriond
gdb -p 1234

(or whatever the process ID was. Freeorion spawns several processes; freeoriond is the server.)

gdb will pause the server when it attaches; 'c' and enter to resume. Play normally. If the daemon crashes, the debugger will pause the process and give the "Program received SIGSEGV" message. Then type 'bt' and enter to get the backtrace. If you don't have gdb installed, your package manager probably keeps it in a package called gdb.

If #1 in the backtrace ISN'T (big hex number) SpeciesManager::GetSpecies(std::__cxx11::basic_string<char, std::char_traits, std::allocator > const&) ()
from /home/gametest/freeorion-git/2019/freeorion/build/libfreeorioncommon.so
then we probably have two different bugs that just look the same from outside.

I'm gonna have to start a new game to be able to run the back trace.

Okay, it seems like we're looking at the same thing. Backtrace:

I can't reproduce a crash with the provided saves with (nearly) the latest master. Might be compiler or OS specific. The provided logs appear to be from different runs of the client and server, so I'm not able to determine much from them.
