+Subject: [PATCH] Fix memleak in libverto:vfree
+
+verto_set_allocator(resize, hierarchical) has an unducumented
+requirement on allocator function resize, that resize(ptr, 0) is
+equivalent to free(ptr).
+
+Some implementations of the default allocator realloc don't meet this
+requirement. realloc(ptr, 0) may return a unique pointer that can be
+successfully passed to free. This new pointer never gets freed and the
+memory overhead leaks.
+
+This fix replaces realloc(ptr, 0) with free(ptr) in vresize and
+documents the allocator requirement.
+
+[rharwood@redhat.com: Cleanup comments slightly]
+Closes: #18
+
+(cherry picked from commit 968d542e83619de9759ac4d8f13df30e1016b6c2)
