I don't know if it is fixed, and I don't have the time to dig into
this again.  (What you quoted was by no means the last part of this
bug thread, BTW.)  I would _not_ assume that this bug has been fixed.
I think someone would need to dig into this, to debug it.

I provided a self-contained repro recipe based on the code at
the time, but it is no longer sufficient because variable
`overriding-map-is-bound' no longer exists, and the underlying
code has changed.

You can close the bug, but I'm not confident it has been fixed.
