I think this was decided that this was a front-end bug.

vrp workaround
There seems to be a combination of front-end and middle-end bugs that cause
this. The attached patch works around the problem in vrp by setting the range
to VARYING.

This is a showstopper; ICE on simple, valid code. We need to resolve what
approach (es) to use to fix this and get it done.
