My project application runs smoothly when built in release mode.
However, when it is run after building in debug mode, I get a segmentation fault in a line which is very generic and I have been using it as a template.
QApplication app( argc, argv );
The full file is :
#include <QApplication>
#include "mainwindowimpl.h"
int main(int argc, char ** argv)
{
QApplication app( argc, argv );
MainWindowImpl win;
win.show();
app.connect( &app, SIGNAL( lastWindowClosed() ), &app, SLOT( quit() ) );
return app.exec();
}
Back trace is :

Full project can be got at code.google.com/p/qmtsim
I have not been able to figure out what to do as this goes beyond my realm.
Please help me in debugging this, me and my project is waiting to go ahead .
Thanks for your time and co-operation.
