Hmm ... a quick search locates sth. like this in:

src/activeqt/control/qaxserverbase.cpp
src/corelib/global/qglobal.cpp
src/corelib/kernel/qcoreapplication_win.cpp

Are you sure its not a missing implementation in your app?
I faced sth. like this recently, think it was a header file with a static void 
dosth () method in it but the impl. was missing.
Linked fine but failed at runtime.

Check if you use QCoreApplication::installMsgHandler ... maybe thats the 
cause?
