[Fixed] Surprising critical errors during the mission.

[Halleth]

Actor "A" without TU was chosen. I wanted to click on actor "B". however, I missed and I clicked one tile too far.

What should happen: nothing.
What happened: kick with the message:

ufo: src/common/cmodel.c:2026: Grid_MoveLength: Assertion `to[2] < 8' failed.

Tile was at the same level, 1/4 map away from current actor.

I won't be able to reproduce it easily, though.


I encountered also another problem. It ends with a different error code and shows up without any assertions. It happens once per two played maps so very often. I try to move an actor and the game suddenly crashes.

It would be nice if you could translate offsets to function names and line numbers via addr2line.

Meanwhile, I updated UFO:AI so addr2line wouldn't work. However, I encountered the same problem in the most recent revision (r27407):

[Mattn]

the latter reported bug should be fixed - feedback is welcome - also see report https://sourceforge.net/tracker/?func=detail&aid=2910256&group_id=157793&atid=805242

[Halleth]

So far I played only 3 missions, however everything is fine now If I notice something suspicious, I'll report back.

Thanks for your work, guys!
