I'm opening an issue as its fix is too tiny to become a pull request.

Can be solved by renaming the struct to
```c
     struct indirect_contents { 
         size_type capacity; 
         char* indirect; 
     }; 
```
candidate_blocks_by_work.insert(std::make_pair(candidate->nChainWork, candidate));
            }
        }
    }
    
    while (true) {
        if (ShutdownRequested()) break;
        
        LimitValidationInterfaceQueue();
        LOCK(cs_main);
        LOCK(::mempool.cs); 
        if (!m_chain.Contains(pindex)) break;
        pindex_was_in_chain = true;
        CBlockIndex *invalid_walk_tip = m_chain.Tip();
        
        
        DisconnectedBlockTransactions disconnectpool;
        bool ret = DisconnectTip(state, chainparams, &disconnectpool);
        
        
        
        
        
        UpdateMempoolForReorg(disconnectpool,  (++disconnected <= 10) && ret);
        if (!ret) return false;
        assert(invalid_walk_tip->pprev == m_chain.Tip());
