Summary:
db/column_family.h :
79  ColumnFamilyHandleInternal()

CID 1322806 (#1 of 1): Uninitialized pointer field (UNINIT_CTOR)
2. uninit_member: Non-static class member internal_cfd_ is not initialized in this constructor nor in any functions that it calls.
 80      : ColumnFamilyHandleImpl(nullptr, nullptr, nullptr) {}

db/compacted_db_impl.cc:
 18CompactedDBImpl::CompactedDBImpl(
 19  const DBOptions& options, const std::string& dbname)
 20  : DBImpl(options, dbname) {
   	2. uninit_member: Non-static class member cfd_ is not initialized in this constructor nor in any functions that it calls.
   	4. uninit_member: Non-static class member version_ is not initialized in this constructor nor in any functions that it calls.

CID 1396120 (#1 of 1): Uninitialized pointer field (UNINIT_CTOR)
6. uninit_member: Non-static class member user_comparator_ is not initialized in this constructor nor in any functions that it calls.
 21}

db/compaction_iterator.cc:
9. uninit_member: Non-static class member current_user_key_sequence_ is not initialized in this constructor nor in any functions that it calls.
11. uninit_member: Non-static class member current_user_key_snapshot_ is not initialized in this constructor nor in any functions that it calls.

CID 1419855 (#1 of 1): Uninitialized scalar field (UNINIT_CTOR)
