  "message": "Fix two memory leaks in the collocator lookup\n\nEvery collocator lookup leaked a rocksdb iterator and 80 bytes of window sums:\n\nCollocatorIterator takes the iterator that SeekIterator() gets from\nDB::NewIterator(), but had no destructor, so the compiler generated one that\ndoes not touch the raw pointer. The wrapper was deleted by its unique_ptr, the\niterator it wrapped was not, together with everything it pins.\n\nget_collocators() allocated its fixed size sumWindow array with malloc() and\nnever freed it. It is a fixed size, so it lives on the stack now.\n\nMeasured with 20000 calls of get_collocators_as_json() on the test database:\n3.63 kB per call before, no measurable growth at all afterwards. The 80 bytes\nwere per call regardless of the result size, which is what gave them away.\n\nCo-Authored-By: Claude Opus 5 \u003cnoreply@anthropic.com\u003e\nChange-Id: I1b1148ada81bd821784b8e327334fc3bafe29e1b\n",
