That's great. I'm not sure exactly "why" this happens, it shouldn't, but it used to happen in 10.5 as well. I'm pretty sure I rdar'd it, but another bug report couldn't hurt.
My thought is that the in this scenario, the qc evaluation mechanism can't tell that the RII that's upstream (and a subgraph that is a different comp) is programmed to give no values out that first call. It can't deliver a single frame yet, bc it's off to start. Since the render needs a value, and it thinks it should be getting one, stuff freezes up instead of rendering. It looks like it's totally confused about when/what is supposed to be rendering from the crash. I still think it's a bug. It may also be related to some stuff the RII does to keep things that it assumes aren't visible in the viewer from evaluating, from that "dod get bounding rect message" and the consumer graph part (or QCRender, whichever) can't get that to work right when it loads the RII oriented graph part. I'm unsure if that's the method that does that or not, so that's definitely conjecture, but I've had that RII feature cause me many headaches in the past, along with some added sl stuff that makes one have to do stuff like have a patch evaluating in the background in an rii to make feedback loops with an rii work right. The patch could use some love.
