Program crash

[wysota]

Does it work if you remove the qDebug() call? And what happens if you call qDebug() from that other application? Is is a Qt based app?

[Pragya]

Yes it works when I remove it, the other application is Qt application

[wysota]

Again, do qDebug() statements work inside the other app?

[Pragya]

Yes it works.

[wysota]

Did you try debugging?
