Follow-up Comment #7:

dai_plr_data_get() has since been refactored in a way that address most causes
of this assert. Closing this bug assuming that its root-cause is one of the
handled ones. Open new tickets about cases that still make assert to fail.

Follow-up Comment #6, bug #18333 (project freeciv):

bug #18461 has another case where action of one player causes another one to
need its data, even if it's not its phase: conquering enemy capital can cause
civil war for him/her.

I get this assertion failure within two turns upon every load (4 so far) of
the attached savefile.

Follow-up Comment #4, bug #18333 (project freeciv):

phasemode in this game is Team. It seems that same player for some reason
gets second opportunity to move (two phases given to him) in same turn when
problem occurs.

Follow-up Comment #5, bug #18333 (project freeciv):

After some more debugging I no longer think that player gets several phases,
I just misunderstood when turn had changed.

Basic reason for this error seems quite clear. When phasemode is some
alternating one, data phases (both advisors and default ai ones) are not open
for all players simultaneously. Current ai can cause another one, for which
data phase is not open, to evaluate treaty.
I think we have more similar problems where actions of one ai (whose phase it
is) can cause other ai to do something out of its phase. Diplomatic incidents
at least are likely to have this problem.

Follow-up Comment #1:

It sounds like you're talking about trunk (as there's no file/function named
like that in S2_3).

Bug #18095 was closed by suppressing the assertion failure on S2_3 only
(trunk was unchanged). The failure there was not reproducible on trunk.

I had a quick poke at this revision and didn't see anything of the kind after
29 turns with the default ruleset and aifill 7. Can you provide a savegame
from which it can be reproduced? Failing that, can you get a backtrace with
-F?
