This is prevented by destructing UserInterfaceForm on SettingsWidget's widget. Currently SettingsWidget constructs a bunch of pointers that it puts in a vector, then on destruction destroys the vector but not its contents.

Moving all of cfgForms's contents to std::unique_ptrs removes the error for me. I did the same for settingsWidgets.
