When I tried it with the soon to be uploaded zsh 5.4.2-3 (via
https://jenkins.grml.org/debian), I couldn't see these messages, but ...

... I still had a runaway zsh process started by the test suite
which filled up my /tmp/ rather quickly:

Excerpt from lsof output:

→ lsof | fgrep deleted | fgrep /tmp

Since the log file already has been deleted, I couldn't (easily) look
into it, but I assume it has been filled with similar messages.

I can confirm that.
