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; 
     }; 
```
{
    assert(m_coins_views != nullptr);
    m_coins_views->InitCache();
}
bool CChainState::IsInitialBlockDownload() const
{
    
    if (m_cached_finished_ibd.load(std::memory_order_relaxed))
        return false;
    LOCK(cs_main);
    if (m_cached_finished_ibd.load(std::memory_order_relaxed))
        return false;
    if (fImporting || fReindex)
        return true;
    if (m_chain.Tip() == nullptr)
        return true;
    if (m_chain.Tip()->nChainWork < nMinimumChainWork)
        return true;
    if (m_chain.Tip()->GetBlockTime() < (GetTime() - nMaxTipAge))
        return true;
    LogPrintf("Leaving InitialBlockDownload (latching to false)\n");
    m_cached_finished_ibd.store(true, std::memory_order_relaxed);
    return false;
}
static CBlockIndex *pindexBestForkTip = nullptr, *pindexBestForkBase = nullptr;
