uniqCombined() uses hashtable for medium cardinality, and since HashTable resize by the power of 2 (well actually HashTableGrower grows double by the power of 2, hence HashTableGrower::increaseSize() should be overwritten to change this), with 1<<13 (default for uniqCombined) and UInt64 HashValueType, the HashTable will takes: getBufferSizeInBytes() == 131072 While it should be not greater then sizeof(HLL) ~= 98K, so reduce the maximum cardinality for hashtable to 1<<12 with UInt64 HashValueType and to 1<13 with UInt32, overwrite HashTableGrower::increaseSize() and cover this using max_memory_usage.
