--- Comment #7 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Thanks for the analysis and for the reduced testcase.

> This might have the same root cause as 93154, as in both cases, it looks =
like the compiler is mixing up the template arguments of the outer function=
 and the inner lambda.

I think you're right.  PR92633 contains a smaller testcase whose root cause=
 is
the same, and after fixing that PR (for GCC 10.2+) we now also correctly
compile the original testcase here.  So I'm marking this PR as a dup of
PR92633.
