Compiler panic on renaming a struct

[danielkeller]

I got a compiler panic when renaming a struct from StackPos to Reg. It went away when I ran cargo clean, and didn't come back, so I'm not sure how to reproduce it.

Closing assuming the previous "it's a duplicate" is correct, because it seems so to my eyes.
