Description
short summary of the bug:
Unexpectedly the compiler return an error.
I compile on WSL1 Debian on Win10.
I tried this code in this commit:
https://github.com/LucianoBestia/crates_io_database/commit/18b625fe64c4a54d871fc0f21ad6e6994dc11fab
code sample that causes the bug:
I run this command:
$ clear; cargo test
I expected to see this happen:
tests pass or fail.
Instead, this happened:
