- Operating System set to Windows 8.1, 7 x64
1. start QGIS
2. open Spatial Bookmarks
3. if panel is docked, undock it so it is a separate window (the little button or just drag it off the main window)
4. close QGIS (I normally use the close button, but have tried Exit on the Project menu, too)
Perhaps I could have been more specific about using Windows 8.1 and Windows 7, both x64 systems.
I tried OSGeo4W builds as well as my own builds which are based on OSGeo4W libraries, etc.
And I didn't experience the crash if other dockwidgets are floating, specifically GPS Information and Python Console.

After comparing QgsBookmarks code before and after the recent changes, I believe the QgsBookmarks destructor should delete mProxyModel, either directly or through lstBookmarks->model(), rather than deleting mQgisModel.
I have tried this in my own building of master and 2.18.15 and no longer get the crash.

Nevermind: mQgisModel must be deleted otherwise it would leak, btw the order of destructors does matter here, so I'm now deleting the proxy model directly instead of leaving it to the parent (which is now a nullptr).
Btw, if you can take care of backporting my latest fixes to 2.18 it would be much appreciated.

PR filed: https://github.com/qgis/QGIS/pull/6032
I have tested the changes in 2.18 from having no bookmarks to exporting and importing bookmarks, setting project bookmarks, and deleting both QGIS and project bookmarks. And no crash on closing QGIS if the bookmarks panel is floating.
