[Qt-interest] Qt with x64 computer

[P B]

Hi,
 
   I am new to Qt, using an open source version. I am going to work on a program from someone else that used Qt with a 32 bit computer. Everything works well for him but I have problems. I'm using Visual Studio 2008 to create a personal application that will use Qt. Qt was compiled with Visual Studio 2005. 
 
   - fixed: First I used to have "dll not found" problems but that is cleared when I recompiled Qt locally and I can now see a Qt window when debugging.
 
   - Now I have a problem and do not know where to look: In debug mode, in the opened window created with my application, I click a button to load a file. The application gives an error when loading a simple .txt file. The error says there was a stop to the exe probably caused by a stack problem from a loaded dll. Is there still a problem with Qt and x64? The debugger stops at : 
 
qhash.h
 
in the function:
template <class Key, class T>
Q_OUTOFLINE_TEMPLATE typename QHash<Key, T>::Node **QHash<Key, T>::findNode(const Key &akey,
uint *ahp) const
 
 
at line : 
while (*node != e && !(*node)->same_key(h, akey))
 
 
Thanks for any help, or hints for what could be the problem,
Pascale
 
 
 
Note: Here is the error message, sorry my vs is in French:
 
Windows a déclenché un point d'arrêt dans drop2dd.exe.
Cela peut être dû à une défaillance du tas qui indique un bogue dans drop2dd.exe ou l'une des DLL chargées.
Cela peut également être dû à l'appui sur la touche F12 lorsque drop2dd.exe a le focus
La fenêtre Sortie peut contenir des informations de diagnostic supplémentaires.
