Hi Raphael

I have investigated a similar issue in the past (CVE-2016-7543). That time
it was the PS4 variable and the default shell an important factor. If I had
dash as default shell it was possible to reproduce the issue. If I had bash
as default shell it was possible.

As this is a prompt expansion and that tend to be handled differently in
different shells I thought that maybe the default shell could be important
in this case too.

This is why I suggested to check what shell was the default shell.

Yes it was speculation, but backed by the fact that I have stumbled on that
kind of problem in the past.

Best regards

// Ola
