Hi,
this patch fix a stupid thinko that could generate garbage: some index block were freed in the reverse order.
Also, these blocks are cleared when allocated to make the output deterministic.
Committed on trunk.
Tristan.

* vms-lib.c (vms_write_index): Fix thinko: reverse the loop.
Use bfd_zmalloc instead of bfd_malloc. Fix comment.
