It's possible to create a FrameInformation object that's not backed by any frame data. In this case, fi_ is NULL and loadFrameTree() does not run a dissection. However, we run epan_dissect_cleanup() unconditionally in the destructor, even if edt_ is uninitialized. This causes a crash when wireshark is closed. Convert edt_ into a pointer. Run the cleanup only if we ran the dissection before. The issue can be reproduced by applying a display filter that makes the list of the packets smaller than the packet list window. Right click onto an "empty" part of the packet list and select "Mark/Unmark Frame". Exiting wireshark at this point causes a segmentation fault Thread 1 "wireshark" received signal SIGSEGV, Segmentation fault. tvb_free_chain (tvb=0xf000e000d000c) at ../epan/tvbuff.c:124 124 tvb_free_internal(tvb); (gdb) bt #0 tvb_free_chain (tvb=0xf000e000d000c) at ../epan/tvbuff.c:124 #1 0x00007ffff430491e in epan_dissect_cleanup (edt=0x555558075b48) at ../epan/epan.c:648 #2 0x00005555558fa5a6 in FrameInformation::~FrameInformation (this=0x555558075b20, __in_chrg=<optimized out>) at ../ui/qt/utils/frame_information.cpp:57 #3 0x00005555558fa5e9 in FrameInformation::~FrameInformation (this=0x555558075b20, __in_chrg=<optimized out>) at ../ui/qt/utils/frame_information.cpp:55 ... #12 0x00005555559a74f7 in PacketList::~PacketList (this=0x55555602e930, __in_chrg=<optimized out>) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qstring.h:1130 Change-Id: I347dd4901b4e08c37008ff25ac1f20a67555d9fd Reviewed-on: https://code.wireshark.org/review/36825 Reviewed-by: Martin Kaiser <wireshark@kaiser.cx> Petri-Dish: Martin Kaiser <wireshark@kaiser.cx> Tested-by: Petri Dish Buildbot Reviewed-by: Anders Broman <a.broman58@gmail.com>

In the constructor, we allocate a delegate for the name column and assign
it by calling QAbstractItemView::setItemDelegateForColumn(). This does
not pass ownership of the delegate to QAbstractItemView, it's still
up to us to free the delegate.
ASAN warns about this
Indirect leak of 48 byte(s) in 1 object(s) allocated from:
...
#1 ... in ProfileTreeView::ProfileTreeView(QWidget*) ui/qt/widgets/profile_tree_view.cpp:46:17
#2 ... in Ui_ProfileDialog::setupUi(QDialog*) ui/qt/qtui_autogen/include/ui_profile_dialog.h:67:31
#3 ... in ProfileDialog::ProfileDialog(QWidget*) ui/qt/profile_dialog.cpp:59:13
#4 ... in MainWindow::on_actionEditConfigurationProfiles_triggered() ui/qt/main_window_slots.cpp:2239:36
Add a destructor for ProfileTreeView and free the delegate there.
