Hi Martin,
Thanks for fixing my issue.  The IVO part of patch is OK.
Just for me to understand, iv_common_cand is freed via free_ptr_hash,
and thus typed_free_remove.  So what leaks is the iv_use * vector in
struct iv_common_cand, right?  I did forget to free that.
BTW, how do you monitor memory use in GCC, maybe I can run same test
for my future patches.
