QT application run-time error

I've been writing an application using QT 3.2.3 for Cygwin.  It was 
compiling and running just fine until I tried using signals and slots. 
As soon as I added a declaration for a public slot, the application 
crashes at run time with the popup error message "The application failed 
to initialize properly (0xc0000005).  Click on OK to terminate the 

If I comment out the contents of the function implementation, the error 
still occurs.  If I don't connect the signal and slot, the error still 
occurs.  But if I move the function declaration to a simple public 
section in the class, the run-time error does not occur.  I can compile 
and run my code under Linux without any issues.  Has anyone else had 
this or a similar problem occur?

Here's the software versions I'm using:

Package  Version
-------  -------
Cygwin   1.5.11
GCC      3.3.3 (cygwin special)
QT       3.2

Here's the class definition with the declared slot:

#include <qlistview.h>

class FileTree : public QListView

     FileTree(QWidget* parent);

   public slots:
     void fillDir(QListViewItem*);

     QString getItemPath(QListViewItem*);
