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; 
     }; 
```
{
    AssertLockHeld(cs_main);
    const CCoinsViewCache& coins_cache = CoinsTip();
    assert(!coins_cache.GetBestBlock().IsNull()); 
    const CBlockIndex* tip = m_chain.Tip();
    if (tip && tip->GetBlockHash() == coins_cache.GetBestBlock()) {
        return true;
    }
    
    CBlockIndex* pindex = LookupBlockIndex(coins_cache.GetBestBlock());
    if (!pindex) {
        return false;
    }
    m_chain.SetTip(pindex);
    PruneBlockIndexCandidates();
    tip = m_chain.Tip();
    LogPrintf("Loaded best chain: hashBestChain=%s height=%d date=%s progress=%f\n",
        tip->GetBlockHash().ToString(),
        m_chain.Height(),
        FormatISO8601DateTime(tip->GetBlockTime()),
        GuessVerificationProgress(chainparams.TxData(), tip));
    return true;
}
