Here are the code lines containing the variable in question:

        void *item;
        while ((item = hashmap_iter_next(&iter)))

Intriguing.  The variable "item" is set, but can be removed without
effect.  GCC 7.2 and Clang 5 don't warn about that.

The code was introduced by 8b604d1951 (hashmap: add API to disable item
counting when threaded) and there is no patch in pu that touches it
again, yet.
