memory leaks

[Mat]

Also das Programm/die Application läuft problemlos,nur valgrind meldet also die fehlermeldungen!
Ich lege NUR QT Widgets auf dem Heap ab! Nix eigenes was ich deleten müsste....
diese meldung:

kommt schon beim aufruf der Anwendung.
ÜBrigens: wenn ich Beispiele von der trolltech homepage oder NUr eine leere Anwendung ausführe kommt dieser fehler auch!
dabei steht in der zeile 15 der UIMain.cpp nur




QApplication app( argc, argv );



ist das ok so?


wie könnte ich eben an diese fehler rangehen, die erst NACH dem beenden der Anwendung auftreten:

wäre nett wenn mir jemand helfen könnte...

Das dürfte in der XLib sein, da kannst du nichts machen, allerdings sind das meiner Erfahrung nach keine anwachsenden Leaks.

Ciao,
