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; 
     }; 
```
AssertLockNotHeld(cs_main);
    
    
    
    
    LOCK(m_cs_chainstate);
    CBlockIndex *pindexMostWork = nullptr;
    CBlockIndex *pindexNewTip = nullptr;
    int nStopAtHeight = gArgs.GetArg("-stopatheight", DEFAULT_STOPATHEIGHT);
    do {
        boost::this_thread::interruption_point();
        
        
        
        
        
        
        LimitValidationInterfaceQueue();
        {
            LOCK2(cs_main, ::mempool.cs); 
            CBlockIndex* starting_tip = m_chain.Tip();
            bool blocks_connected = false;
