In the `Ranges(...)` generation code a "control" vector which stores the current index for each range passed to `Ranges`. Previously this vector was incorrectly initialized to the size of the subranges not the number of subranges. Additionally this patch suppresses unused warnings generated by `stream_init_anchor`.
