crash dump

Per commented

Got a savegame that can reproduce it?

Buginator commented

Something was changed in the path finding code, and it is screwing things up. I was thinking it has to do with the other patch you did for the path finding recently.

Per commented

I haven't touched the path finding code recently. Which change do you have in mind?

Buginator commented

Replying to Warzone2100/old-trac-import#738 (comment:3):

I haven't touched the path finding code recently. Which change do you have in mind?

My 'recent' means the last code changes you did, I guess it may also can be the 'orders' change as well.

The units either get new orders, and the path list is empty, or the list gets empty by something.

When I come back, I will try to narrow it down a bit more, since the above is only really a guess.

Here's a move.c:384 error and a savegame file that will reproduce it. I built the binary.

To reproduce: Open 'Test14' savegame. System will crash.
