    Description

      The shown ListModel doesn't keep "o" alive, which is a QObject whose ownership is JavaScriptOwnership. I observe that "gc()" yields to a destructor call of the object that "o" references.

      Please use the attached "gc" tarball that contains an example project. Entering Code doesn't appear to work in the Description.

This includes regressions from the last version that are not edge cases; Data loss; Build issues; All but the most unlikely crashes/lockups/hanging; Serious usability issues and embarrassing bugs & Bugs critical to a deliverable.
