    Description

      Both Asan and Valgrind show memory leak in QScroller::grabGesture(QObject*, QScroller::ScrollerGestureType)

       

      From valgrind:
      ==2274392== at 0x4849013: operator new(unsigned long) (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so)
      ==2274392== by 0x61D8469: QScroller::grabGesture(QObject*, QScroller::ScrollerGestureType) (in /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5.15.3)

      From Asan
      #0 0x7f6f39cc81e7 in operator new(unsigned long) ../../../../src/libsanitizer/asan/asan_new_delete.cpp:99
      #1 0x7f6f2f2b6413 in QScroller::grabGesture(QObject*, QScroller::ScrollerGestureType) (/lib/x86_64-linux-gnu/libQt5Widgets.so.5+0x512413)

       

      Calling QScroller::ungrabGesture(QObject*) does not help.

      Qt 5.15.3 and Ubuntu 22.04
