            Bug ID: 25125
           Summary: seg fault on opening the gui twice
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux

Back trace and steps used to create seg fault

Steps to reproduce
    1: Run lldb
    2: Open the ncurses gui
    3: Close the ncurses gui
    4: Open the ncurses gui again

I recently built llvm and friends from the trunk and was reading the
code/playing around with the tools and I found that upon opening the gui
closing the gui and subsequently re-opening the gui, lldb seg faults. See the
attachment for the backtrace and how I generated the seg fault. I have tested
this multiple times and it is reproduceable on my machine. I haven't had the
chance to dig any deeper yet.

lldb --version
  lldb version 3.8.0 (http://llvm.org/git/lldb.git revision
