I'd just like to add that this has been reported by a forum user for his 'galactic ruleset' project, so the crash has been seen 'in the wild': http://forum.freeciv.org/viewtopic.php?t=4196 ~Daniel ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

Find all the issues, describe the range of solutions, and we'll discuss it here As I said, the problem is that fuel=0 is special-cased for air units. Similarly non-air-units, which normally have fuel=0 also, get the fuel set to 1 to make this special-casing work. The full fix then would be to leave fuel at 0 for non-air units. The special case, then, would not be on fuel=0 but rather on fuel0. -jason ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
[Freeciv-Dev] (PR#39941) gravship goto crashes
URL: http://bugs.freeciv.org/Ticket/Display.html?id=39941 Gravships (air units with 0 - unlimited - fuel) crash when goto is invoked. This appears to be caused by the special-casing of the 0 fuel which is not special-cased everywhere. This causes PF to think that the unit actually has 0 moves. Attached is a quick fix but there are other (seemingly non-fatal) bugs with this. For instance it always shows the turns-to-target as 0 for gravships. -jason Index: common/aicore/path_finding.c === --- common/aicore/path_finding.c (revision 14109) +++ common/aicore/path_finding.c (working copy) @@ -134,10 +134,12 @@ with fuel 1 all moves on the same tank of fuel are considered to be one turn.
