Description
Crashing is occurring because of out of range index for during selection change on a table view.
The model in use is a QAbstractItemModel. This wraps a QSqlQueryModel*, which is reloaded async on another thread and emits layoutChanged() when completed. Proper locking and bounds checking is in place with the model. An override of QTableView::selectionChanged() attempts to handle additional bounds checking which does not appear to make a difference.
The crashing has occurred since 6.5.2 and the project was recently upgraded to 6.7 which seemed to improve the situation but it still occurs intermittently.
