[lldb-dev] LLDB-MI from Eclipse hangs

Thanks Ted.
Attached is the GDB log after enabling log while executing same commands
manually from command prompt.

Yes, I am running debug server manually.  I am facing issues with "GDB
(DSF) Automatic Remote Debugging Launcher" as eclipse is not passing
correct parameter to debug server. Below is the Eclipse console output with
automatic mode:

*echo $PWD'>'*
