Branch on a garbage value

[TheQuantumPhysicist]

Clang analyzer shows this error:

Logic error: Branch condition evaluates to a garbage value
1: Calling 'tcp_client::process_write' in tacopie/sources/network/tcp_client.cpp:174
2: Assuming the condition is true in tacopie/sources/network/tcp_client.cpp:218
3: Returning from 'tcp_client::process_write' in tacopie/sources/network/tcp_client.cpp:174
4: Branch condition evaluates to a garbage value in tacopie/sources/network/tcp_client.cpp:176

The value result.success seems never to be initialized anywhere here:

  read_result result;
  auto callback = process_read(result);

  if (!result.success) {
    __TACOPIE_LOG(warn, "read operation failure");
    disconnect();
  }

While I see that process_read() does the initialization, I'm wondering whether there's something else missing.
