[gnugo-devel] disconnect crash (was dynamic connection status)

[Trevor Morris]

The problem is with simple_ladder not dealing well with a double-ko
situation, causing a stack overflow as it flips the kos over & over.
So, not strictly in the connection code, but that's the only code
that calls simple_ladder, so this crash can't occur in play.

I'm going to pass this bug off to someone more familiar with the
simple_ladder code & komaster.

Here's a sample case that causes a crash on a recent build:

loadsgf games/trevor/trevor_75.sgf
750 disconnect O9 O7
