Old versions of xboard and winboard had a real problem in that the internal move list would hold 256 moves. Tim fixed that several years ago when Crafty played games on ICC that hit the 256 move limit and xboard would simply hang and lose on time... I have played games that went well over 300 moves with no known problems, although that does not mean that there is not a bug in Crafty, but since I don't store the game in memory, I can't imagine an overwrite problem.
