[Dev-C++] segmentation fault at runtime

[Black E. <bla...@ea...>]

Hi guys!

I got a problem at run time, when using a pointer in a function.

The error is in the function KviIrcServer* server() at line : return m_pSrv;

In all other functions I got no problem with this variable. It is another 
class that tries to call this function, it's the friendclass beChannel


Here is the beConsole.h

#ifndef BE_CONSOLE_H
#define BE_CONSOLE_H

#include "beMDIWindow.h"

class KviIrcServer;

class beConsole : beMDIWindow
{
	friend class beIRC;
	friend class beChannel;
	Q_OBJECT
public :
	beConsole(QWidget * parent = 0, const char * name = 0, WFlags f = 0);
	~beConsole();
	
	KviIrcServer* server();
protected :
	bool connectToServer();
private slots :
	
	virtual void hostFound();
	virtual void connected();
	virtual void socketReadyRead();
	virtual void disconnected();
	void send(const QString & command);
private :
	KviIrcServer  * m_pSrv;
// 	KviProxy      * prx;
	
	QSocket * m_pQSocket;
};

#endif

And here is the beConsole.cpp
// beIRC stuff
#include "beConsole.h"
// kvirc stuff
#define HAVE_CONFIG_H
#include "config.h"
#include <kvirc/3.0.1/kvi_app.h>

Thanks for any help !
