What matters is that the compare function gives a reliable result. You can't subtract pointers like that for qsort. After consulting the experts on IRC, I'm going with a fix along the lines of "return (x == y ? 0 : (x < y ? -1 : 1));". > Anyways, > how come this is related to your patch? We don't use statistics in > sel-sched... Something got miscompiled? No, just allocated slightly differently. A bitmap_head is one pointer bigger than before. I'm unsure how that causes this problem, though. I suspect you would have seen the same failure with GATHER_STATISTICS enabled. Ciao! Steven
