Check the gdb-remote packet log. It seems you are losing connection to your
lldb-server and that causes the process to die with -1 and "lost connection".
To see the log:
(lldb) log enable -t -f /tmp/packet.log gdb-remote packets
This will log all GDB remote packets, including the ones that the "lldb-server
platform" is sending, but you might be able to see how far your program is
making it...
