Description
openedon Jan 1, 2020
I was migrating my library (Mammut) to use reqwest 0.10 and be async, and the compiler ICEd. I don't know how to reduce it further than this.
I tried this code:
XAMPPRocky/Mammut@f30bdec#diff-b4aea3e418ccdb71239b96952d9cddb6
I expected to see this happen: A successful build or another compile error
Instead, this happened: thread 'rustc' panicked at 'no entry found for key', src/libcore/option.rs:1188:5
Meta
I also tried this on the latest nightly and it emits the same error.
