            Bug ID: 34183
           Summary: Remote debugging ARM linux target from x86 linux host
                    - process launch fails
           Product: lldb
           Version: 5.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

The issue is mentioned on lldb-dev list here
http://lists.llvm.org/pipermail/lldb-dev/2017-August/012594.html.

The remote debugging under the same environment works with lldb v4.0.1.

In lldb v5.0, it appears that GDBRemoteCommunication::StartDebugserverProcess()
is not able to allocate/find new port for the spawned gdbserver which is
evident from the log line

GDBRemoteCommunication::StartDebugserverProcess() debugserver listens 0 port

causing the following error on the client side.

Socket::TcpConnect (host/port = 10.10.2.3)
TCPSocket::Connect (host/port = 10.10.2.3)
error: connect remote failed (invalid host:port specification: '10.10.2.3')
