    Description

      Since iOS 11 was released my application on devices with fresh iOS sometimes got crashed during the work. In QtCreator's output window i got this

      program received signal -111, thread:3201f

      In XCode output window last message before crash:

      ASSERT: "inUse()" in file jsruntime/qv4engine_p.h, line 521
(lldb)

      It usually happes when application successfully connected to server, get data, and starting handle it (with active creation of dynamic qml elements). But all working ok on other iOS versions.

      Here are copy of XCode debug navigator in moment of error
