Just to confirm what you are saying: that the OP's bug report code on
your *blead* causes the panic shown above?

If so, that's a new kettle of fish. The original assumption had been
that the bug was fixed in blead, and the discussion was merely about
backporting a modified version of the "fixing" commit to maint-5.14 and

FWIW, I can't reproduce any failures on blead.

What are the commit and the build options for your blead?
