Short description of error
Hi,
In this .blend below i have a node set up that crash to desktop,
you will see that all the nodes in the Pink frame are not used and should be ignored but they are causing crash.
This is from a brand new build from today 9 march.

Exact steps for others to reproduce the error
On blend below, connect "do_push" with "push_or_not" reroutes.
if the pink frame is connected it will cause crash, if it's disconnected with the node system it will not crash
