Good catch.  Adding

  for (i = 0; i < linear->count; ++i)
    printf("\t%p %d\n", linear->array[i], i+1 < linear->count ?
	   fde_compare (ob, linear->array[i], linear->array[i+1]) : 0);

i.e. compare each entry to the one following.  We should thus
get a sorted sequence with all comparisons == -1.  But instead,

        10025df0 -1
        10025e50 1
        10025e80 1
        10025eb0 -1
        10025ee0 -1
        10025f10 -1
        10025f40 -1
        10025f70 -1
        10025fa0 -1
        10025fd0 1
        10026000 1
        10026030 -1

The numbers are in fact sorted, but the comparisons are wrong.
