need help with LLDB debugger.

[bshi02]

I used LLDB debugger in linux environment(Lubuntu 15.10 Willy Werewolf),but it always show an incorrect local value in watch window.(In contrast,GDB debugger always works great on CodeLite,It doesn't show any incorrect value at all)
I have uploaded a mp4 video file to dropbox cloud which demonstrate an example of incorrect value which was shown in watch windows when I changed it to LLDB debugger.(value of argc must be 2 in both of two debugger, but it is 0 in the LLDB debugger)

Is there anyone who know why this weird result was to be shown in LLDB debugger?

For your information,I used this source code for this example of incorrect value.
