[Qt-creator] Debugger problem with Creator 2.5.81 snapshot

[Stephen Chu]

I am trying out the snapshots which seems to have better C++11 syntax 
support.

I did find a problem with debugger on Mac 
(qt-creator-mac-2.5.81-mac_x86_64-138-2012-08-29_00-00-35.dmg) that when 
moving between stack frames, the variables pane never gets updated.

If I stop at a break point, it shows the variables at that point. But if 
I click at the calling function in the stack, the variables pane remains 
the same. It never updates to the variable of the calling function.

Windows snapshot does not exhibit this problem.
