Description
This test is a small reproducer of a crash we had in production after bumping to the latest Qt version, it passes without issue in 5.15.3, but starting with 5.15.4 it always crashes:
function test_generator_gc() {
((function*() { gc() })()).next();
((function*() { gc() })()).next();
((function*() { gc() })()).next();
((function*() { gc() })()).next();
((function*() { gc() })()).next();
}
I think the regression was introduced by QTBUG-91491: qv4generatorobject: Fix crash when creating new properties (but I haven't tested).
