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; 
     }; 
```
}
        
        
        
        if (nConflictingCount <= maxDescendantsToVisit) {
            
            
            for (CTxMemPool::txiter it : setIterConflicting) {
                m_pool.CalculateDescendants(it, allConflicting);
            }
            for (CTxMemPool::txiter it : allConflicting) {
                nConflictingFees += it->GetModifiedFee();
                nConflictingSize += it->GetTxSize();
            }
        } else {
            return state.Invalid(TxValidationResult::TX_MEMPOOL_POLICY, "too many potential replacements",
                    strprintf("rejecting replacement %s; too many potential replacements (%d > %d)\n",
                        hash.ToString(),
                        nConflictingCount,
                        maxDescendantsToVisit));
        }
        for (unsigned int j = 0; j < tx.vin.size(); j++)
        {
