      Description

      Hi,

      I found a bug in qt when I use QT_DISABLE_DEPRECATED_BEFORE=0x060000

      It's a crash in qlistwidget.

       

      I created a testcase (see attachment)

      Just enable/disable DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000

      bt:

      Thread 1 "crash-qlistwidg" received signal SIGSEGV, Segmentation fault.
