--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Confirmed, thanks for the detailed bug report.

> This may have the same underlying cause as bug 104981. It would not be surprising if some internal compiler code removed the outer reference and expected to be left with a type that is not a reference. I can't preclude this being just a coincidence, however.

You're spot on, the proposed patch in PR104981#c3 seems to also fix this.
