Details:
Observing a game crashes the server upon end turn.
Start a new game, then observe it with a different client using global
observer command.
Press end turn on the playing client, which cases a segmentation faul on the
server.
This is using Freeciv trunk. It also occurs on freeciv-web,
but this build is using an unmodified freeciv trunk build.
gdb output:
Program received signal SIGSEGV, Segmentation fault.
