In #19015 it's been suggested that we add some new compiler warnings to our build. Some of these, such as `-Wunreachable-code-loop-increment`, generate warnings. We'll likely want to fix these up if we're going to turn these warnings on.

```bash
init.cpp:969:5: warning: loop will run at most once (loop increment never executed) [-Wunreachable-code-loop-increment]
    for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) {
    ^~~
1 warning generated.
```

If you want to build master, with `-Wunreachable-code-loop-increment`, you can use something like this:
```bash
./autogen.sh
./configure CXXFLAGS="-Wunreachable-code-loop-increment"
make check
```
{
    LogPrintf("%s: In progress...\n", __func__);
    static RecursiveMutex cs_Shutdown;
    TRY_LOCK(cs_Shutdown, lockShutdown);
    if (!lockShutdown)
        return;
    
    
    
    
    util::ThreadRename("shutoff");
    mempool.AddTransactionsUpdated(1);
    StopHTTPRPC();
    StopREST();
    StopRPC();
    StopHTTPServer();
    for (const auto& client : node.chain_clients) {
        client->flush();
    }
    StopMapPort();
