Crash under win32

[Andreas Pakulat]

Hi,

I had hoped I could blog about kdev4 on win32 again today, but
unfortunately opening a project fails currently. Its a crash deep in
duchain, from the cmake manager. The backrace is below, its not very
extensive, but at least has line information (though they seem to be off by
one). Basically it crashes inside syncFromSmart when creating the mutex
locker. At the end after the backtrace you can see the this pointer inside
::range and ::syncFromSmart. As you can see the m_smartRange and
m_smartMutex are both 0, so somethings wrong

I need some help here as I basically have no idea where to start looking.
