Bug? attempted to read from stolen value: rustc_middle::mir::Body #100170
Description
I can't currently provide the code, but the rest of the information is below.
I'll try to provide a minimal example when I'm able to.
Please let me know if there's anything else I can do to help (this is my first bug report to this repo).
