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
```
{
    
    
    
    if (!LockDataDirectory(false)) {
        
        return false;
    }
    return true;
}
bool AppInitMain(const util::Ref& context, NodeContext& node)
{
    const CChainParams& chainparams = Params();
    
    if (!CreatePidFile()) {
        
        return false;
    }
    if (LogInstance().m_print_to_file) {
        if (gArgs.GetBoolArg("-shrinkdebugfile", LogInstance().DefaultShrinkDebugFile())) {
            
            
            LogInstance().ShrinkDebugFile();
        }
    }
    if (!LogInstance().StartLogging()) {
            return InitError(strprintf(Untranslated("Could not open debug log file %s"),
                LogInstance().m_file_path.string()));
    }
    if (!LogInstance().m_log_timestamps)
