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);
    LOCK(m_pool.cs); 
    Workspace workspace(ptx);
    if (!PreChecks(args, workspace)) return false;
    
    
    
    
    PrecomputedTransactionData txdata;
    if (!PolicyScriptChecks(args, workspace, txdata)) return false;
    if (!ConsensusScriptChecks(args, workspace, txdata)) return false;
    
    if (args.m_test_accept) return true;
    if (!Finalize(args, workspace)) return false;
    GetMainSignals().TransactionAddedToMempool(ptx);
    return true;
}
} 
static bool AcceptToMemoryPoolWithTime(const CChainParams& chainparams, CTxMemPool& pool, TxValidationState &state, const CTransactionRef &tx,
                        int64_t nAcceptTime, std::list<CTransactionRef>* plTxnReplaced,
                        bool bypass_limits, const CAmount nAbsurdFee, bool test_accept) EXCLUSIVE_LOCKS_REQUIRED(cs_main)
