Ich kann es nicht kompilieren aber unter Linux wäre 'valgrind' das Tool der Wahl...

Was steht denn im Stacktrace wenn du debugst?

Es ist häufig so das der Code sich erst im Qt Bereich "aufhängt" aber die Ursache in einer von dir geschriebenen Funktion/Methode ist.

Also der Fehler kommt nicht von meinem Code:

Endlich mal mit valgrind geschaut??

theprogrammer12 hat geschrieben:könnte es sein, dass ich qt irgendwo einen Pointer mitgegeben habe, dessen Objekt es aber nicht mehr gibt?
Sag mal ist das jetzt unser oder dein Problem?
Du hast bisher keine einzige Zeile code gepostet (nein, ich lade mir keine archive herunter, um stundenlang die entsprechende Zeile zu suchen),
auch noch nicht wirklich viel zu dem Problem gesagt ausser was du nicht weisst.

Wo genau kommt der Fehler also?
Was hast du bisher getan, um die ursache zu finden?
Welcher Code versagt dieses Verhalten? usw. usf.

Alles auskommentieren und stückweise einkommentieren.
Wenn die Anwendung hängt, den Teil wieder auskommentieren denn Du grad einkommentiert hast. Gehts wieder hast Du die Stelle gefunden.

Auskommentieren = Kommentarsymbole vor Code schreiben
Einkommentieren = Kommentarsymbole vor Code entfernen
