      I've been struggling for awhile with Qt Creator crashing randomly while I'm debugging my app on MacOS Mojave. It always seems to crash at a call to Debugger::Internal::QmlInspectorAgent::onResult().

      I've attached an abbreviated .crash file.

      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.

      This has been happening for probably several versions prior to 4.9.2, but I haven't paid close attention to exactly when I first saw it.
