This is a known bug in FSF gnat, triggered by the compiler option
-gnat2020.

The only workaround is to use Community GNAT 2019 or 2020 (from
https://www.adacore.com/download), or possibly an earlier FSF version.

I only test with Community or Pro (supported) versions of GNAT.

In the past I've mainly focused on professional users of Ada (with
support contracts); I need to pay more attention to newbie issues.

I'm hoping the next release will be friendlier by providing pre-compiled
executables that download automatically (with confirmation).
