      Description

      This is a similar crash in QODBC like the one fixed in QTBUG-43889 for QPSQL - when a QSqlQuery is destroyed but the QSQlDatabase was already removed, the app crashes. It was first reported here: https://forum.qt.io/topic/107464/qsql-database-segment-fault.

      Here the backtrace for reference:
