Update your Qt to newer version.
And in general don't worry,
valgrindtends to report false positives when it comes to Qt libs. -

@nagaraj_r since the ui object is created on the heap (using new) and has no parent, it has to be deleted manually. You should add delete ui; to the destructor of the halconform class. Or - better - make use of the smart pointers, like std::unique_ptr. This is independent of the used Qt version.
valgrind reports the memory leak correctly.
