This is not a regular operation, right?

There are many ways to fool yourself.
Try "env TMPDIR= chroot" next time.

It is one of operations when:
- the stress is usually above usual;
- weird diagnostics don't really help.

I'll sure forget it 'till next time.

Rather wanted to draw your attention to the fact that corner cases like this do matter; is it unreasonable to request that directory existence[/writability] check be performed before setting TMP/TMPDIR?

Lets handle this issue in chroot(1).

Thanks in advance!
