Code
This error happened when rebuilding code after changing a proc macro that was used in my crate.
It did not persist after cargo clean, so it may be an issue with the incremental build? I am no longer sure that I can create a minimal example since I can't reproduce after cargo clean.
I am not sure how helpful this well be, but since the error asked me to post an issue I figured I would post what I can.
Meta
This was on the stable compiler

Error output
This error occurred during cargo build, after rebuilding a changed proc macro successfully, and then attempting to build my crate which uses the proc macro. Here's my error output
