connect() terminates the program

[saman_artorious]

I get a weird program termination when I use connect() in my code. I checked the code properly, i don't know where the mistake comes from:

I call construct the control object in MainWindow and call its init()

void Control::initObjects()
{
    logger  = new ErrorLogger();
 
   X    = new Xr();
 
   Y  = new Y();
 
    Z = new Z();
 
    rs_485  = new rs485();
 
    establishConnections();
}
 
void Control::establishConnections()
{
    connect(X       , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
    connect(Y       , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
    connect(Z       , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
    connect(rs485 , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
}

void Control::initObjects()
{
    logger  = new ErrorLogger();

   X    = new Xr();

   Y  = new Y();

    Z = new Z();

    rs_485  = new rs485();

    establishConnections();
}

void Control::establishConnections()
{
    connect(X       , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
    connect(Y       , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
    connect(Z       , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
    connect(rs485 , SIGNAL(logMessage(const char* )), logger, SLOT(logMessage(const char* )));
}

To copy to clipboard, switch view to plain text mode 

the last connect terminates my program, thought the first 3 work properly.

Can't be because of rs485!!?? because you've made an object with name of rs_485. but you have used it with name of rs485 which is the class name. That could be the mistake

That was changed after pasting. it still jumps out when it is run.

Seems somethings wrong with rs_485. Can't tell what is it unless you provide a simple example (attach simple source code)
