At that point, I was adding a function to common.adb and common.ads; upon recompiling, the bug appeared. When I restored those files from backup, the problem remained. To be clear, the "limited with" has been present for a long time with successful compilation until 2-3 days ago.

That is correct. Only after experiencing the problem with what I believe is the original code did I remove the limited with, and the problem remains without the limited with.

I did that. Multiple times. No help.

I thought about that but I'm not sure how to do it. I guess the easiest way would be to make a new directory and put copies of the needed files in it so I don't have to make a bunch of weird switches.

Wow. Good to know.

Not sure what the Mac/ARM situation is with V11.
