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; 
     }; 
```
{
        this->Log(strprintf("%s completed", m_title));
    }
    void Log(const std::string& msg)
    {
        const std::string full_msg = this->LogMsg(msg);
        if (m_log_category == BCLog::LogFlags::ALL) {
            LogPrintf("%s\n", full_msg);
        } else {
            LogPrint(m_log_category, "%s\n", full_msg);
        }
    }
    std::string LogMsg(const std::string& msg)
    {
        const auto end_time = GetTime<std::chrono::microseconds>() - m_start_t;
        if (m_start_t.count() <= 0) {
            return strprintf("%s: %s", m_prefix, msg);
        }
        std::string units = "";
        float divisor = 1;
        if (std::is_same<TimeType, std::chrono::microseconds>::value) {
