Possible memory leak

[klebertarcisio]

Hi everyone,

I would like to know where this data is deallocated.

neper/histo.c

Lines 457 to 474 in 2dd28d3

	struct neper_histo_factory *neper_histo_factory(const struct thread *t,
	int num_buckets, double growth)
	{
	struct histo_factory_impl *impl =
	calloc(1, sizeof(struct histo_factory_impl));
	struct neper_histo_factory *factory = &impl->factory;
	factory->create = neper_histo_factory_create;
	factory->fini = neper_histo_factory_fini;
	impl->thread = t;
	impl->num_buckets = num_buckets;
	impl->ceil = calloc(impl->num_buckets, sizeof(int));
	histo_hash(num_buckets, growth, impl->ceil);
	return factory;
	}

This pull request tries to fix a possible memory leak.
