Desperate QString problem

[onegun]

I have been spending hours on solving the problem, searched doc and google, but cant find a valid solution

int a=0;
    while (a<2)
    {
        //infos.stops is point to one array, called abc[10]
 
        output = output + QString::fromStdString(*infos.stops)+ "." ;
 
        infos.stops++;
        a++;
    }
    ui->showMsg->setText(output);

int a=0;
    while (a<2)
    {
        //infos.stops is point to one array, called abc[10]
    
        output = output + QString::fromStdString(*infos.stops)+ "." ;
    
        infos.stops++;
        a++;
    }
    ui->showMsg->setText(output);

To copy to clipboard, switch view to plain text mode 

the problem is infos.stops did show, but some funny characters appear like link removed.

i have uploaded all my source code which is designed in QT Designer link removed the problem line is at manager.cpp line 133
