Is the problem reproducible from the savegame? If yes, please attach the savegame.

Absolutely consistent.

Load the attached savefile, click "turn done" and it booms.

Not for me, it doesn't. Clicked 'turn done' a few times and no crash or any unusual messages on both client and server.

So, we need to ask you what operating system are you using and which version of freeciv it was.

Sorry, you did report the freeciv version.

I can reproduce and backtrace shows SIGFPE (likely division by zero) at daidiplomacy.c:333

That is:

int limit = MAX(1, player_tech_upkeep(pplayer)

/ research->techs_researched);

I, too, get the coredump in S2_6 (I was looking with S3_0 when I had no problem). I didn't have debugging to give a good bt, so I'm busy building that now.

The patch works for me. No more core dump.
