I came across a consistence crash when using Usd Reference node in Houdini.
Steps to repo:
1- Create a Reference Node
2- Add whatever USD file in "Reference File"
3- Under "Destination Primitive" category, check on "Make Instance"
4- Now check off "Make Instance" and then check on again
5- Crash
I have a call stack that may help for further investigation

I am using Houdini Core 18.5.696 and can repo it both on my Linux and Windows machines.
