[Qt 4.4 + Eclipse] My QT lib makes me crash ( 0xc0000005 )

[bunjee]

Hey there,

I'm starting a new project built around the following approach:

LIB_ITEM - A QT library of widgets.
CORE_PROGRAM - The Core of the program using that Qt library.

* Inside of my LIB_ITEM I have a widget declared as qtBox, it does nothing except having a ctor + dtor.
* Inside of my CORE_PROGRAM I declare a widget which inherits of qtBox.

Now, for some reason when running my CORE_PROGRAM :

-> If I provide the lib DLL, I get a crash before the main is even reached.
-> If I don't provide the lib DLL, I get a symbol's missing crash.
-> If I don't inherit and use the lib, it doesn't crash.

What bugs me is the fact that even if I don't do anything in my main, the program still crashes when linked to my LIB_ITEM.

Any idea ?
