This might be a duplicate of #83628, though this bug requires the flag -C opt-level=3.

jyn514 · 2021-03-29T18:17:45Z

This might be a duplicate of #83628, though this bug requires the flag -C opt-level=3.

I can reproduce without -C opt-level=3, although the error is different:

Global is external, but doesn't have external or weak linkage!

If I add pub, I get the ICEs in debug mode as well: https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=ff07815db1102032bf1dc1e67f20ebff
