Thanks for the report @serzhiio! Looks like this was an inadvertent regression which will be fixed on the next nightly rust-lang/rust#63651

[jstarry]

We can leave this open until we confirm that nightly is fixed again

[serzhiio]

Compiling with '+stable' option is working as intended.

Latest nightly has no errors when building!
