declaration requires an exit-time destructor [-Werror,-Wexit-time-destructors]

  c++, clang, gcc, webrtc

What I am trying is to compile WebRtc Library for android and I am getting this mind blowing error. Please if someone could assist me in this matter. I have these implementations:

stream_buffer.h

  std::list<unsigned char> temp = std::move(buf);
​
  if (buffer.find(ssrc) == buffer.end()) {
    buffer.insert(std::pair<uint8_t, std::list<uint8_t>>(ssrc, temp));
  } else {
    buffer.find(ssrc)->second.push_back(temp.front());
    std::cout << "SSRC: " << ssrc

      for (auto v : buffer[int(it->first)]) {
        std::cout << int(v) << ' ';
      }
      std::cout << "n";
      buffer.find(it->first)->second.pop_front();
    } else {
      std::cout << "Empty buffer for " << it->first << 'n';
    }
  }
}
​
std::list<unsigned char> stream_buffer::get_payload(
    stream_buffer::uint8_t ssrc) {
  if (buffer.find(ssrc) != buffer.end()) {
    return buffer[ssrc];
  } else {
    std::cout << "nstream_buffer.cpp -> Invalid SSRC.n";
    return static_cast<std::list<unsigned char>>(0);
  }
}
​
void stream_buffer::get_buffer_stats() {
  std::cout << "nstream_buffer.cpp -> stream_buffer stats:n";
  for (auto it = buffer.begin(); it != buffer.end(); ++it) {
    if (buffer.find(it->first) != buffer.end()) {
      std::cout << "SSRC: " << int(it->first)
                << " bufferSize: " << buffer.find(it->first)->second.size()
                << 'n';
    }
  }
}
}

Basically I have declared a static map in one the above class with the name of stream_buffer::buffer.
When I try to compile the library, I am getting the following error.

on this line in stream_buffer.cc file.

std::map<unsigned char, std::list<unsigned char>> rtc::stream_buffer::buffer = {};

I have already visited multiple stack overflow issues, but didn’t find anything useful.

  1. How to deal with “exit-time destructor” warning in clang?

I would much appreciate being pointed in the right direction on either issue.
