Thanks, for the repairing. So far, it looks promising. We all should ignore your remark above: Memory is not consumed because of fragmentation. Memory manager efficiency (and only in the very end effectiveness) is killed by it. True. Yet, in a simple application like Scid this need not happen. I will continue some efforts to improve in this respect.
