fwiw, i see it semi often when dealing with build systems:
The unlikely scenario is somehow deleting a non-empty directory, as the

i'm aware of how it's happening.  my point is that it's not completely
unheard of, so i cited the real world cases where it comes up.  and at
least for me, on a semi-regular basis.
We're not talking about the same thing.  The scenario you presented --
removing the entire directory tree including the shell process's current
directory -- is not all that uncommon.  The unlikely scenario I refer to
is somehow -- I'm not sure how -- removing a directory's parent without
removing the directory itself first, which is what the OP's first message
implied he managed to do.  I don't see that scenario ever happening.  It's
unlikely.

Chet Ramey: I fear you have misunderstood me (OP). What I meant was, exactly as you say, the parent AND current folder has been removed, but from a different shell. It's also reprodusable if you do something like this from within the same shell:

mkdir -p ~/a/b
cd ~/a/b
rm -rf ~/a
cd ..

Can you see if that produces the same error? It sure does here.
