Commit ID 2a98042c21fa2f3f5630c41a16b91539d7da3b87
Author Marco Costalba

Fix a crash when 'go' multiple times Search is started after setting a position and issuing UCI 'go' command. Then if we stop the search and call 'go' again without setting a new position it is assumed that the previous setup is preserved, but this is not the case because what happens is that SetupStates is reset to NULL, leading to a crash as soon as RootPos.is_draw() is called because st->previous is now stale. UCI protocol is not very clear about requiring that a position is setup always before launching a search, so here we easy the life of GUI developers assuming that the current state is preserved after returning from a 'stop' command. Bug reported by Gregor Cramer. No functional change.
