> This is because Framework::send proceeds if the framework is disconnected. In

> The executor to framework path does not guard against the framework being
> disconnected, unlike the status update path:

> It was reported that this crash didn't occur for the user on 1.2.0, however
> the issue appears to present there as well, so we will try to backport a test
