Planned maintenance has been done but it did not solve the problem. So work will continue on this and a new time for trying updates will be announced asap.

Qt Creator randomly crashing at Debugger::Internal::QmlInspectorAgent::onResult()



  • I've been struggling with Qt Creator crashing randomly while I'm debugging my app on MacOS Mojave. It looks as if my QML code is at fault. And it always crashes at a call to Debugger::Internal::QmlInspectorAgent::onResult(). I've attached an abbreviated .crash file. Any ideas how to pinpoint where the bug is in my QML?

    @AaronC said in Qt Creator randomly crashing at Debugger::Internal::QmlInspectorAgent::onResult():

    Any ideas how to pinpoint where the bug is in my QML?

    QtCreator should not crash because of some QML code.
    Did you file a bug in Qt bug tracker?



  • I will submit a bug report. My hunch is that my QML is getting bad data from one of my models, causing QmlInspectorAgent to crash out. Because this causes Qt Creator to just go away, it leaves me no breadcrumbs to help pinpoint the problem. So far, instrumenting my code hasn't helped me find the bug. Besides instrumenting my models, any other ideas how to figure this out?
