--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Looks like a failure to call resolve_nondeduced_context.  I have a patch.

    c++: Deducing type from initializer_list<auto> [PR93107]

    In this testcase we weren't able to deduce b's type:

      template<typename T> void Task() { }
      auto b = { &Task<int> };

    because resolve_nondeduced_context doesn't iterate on the {}'s elements.
    So make sure to look into {} too.  We don't need to handle nested {}
    here.

    We could either tweak resolve_nondeduced_context to handle CONSTRUCTORs
    or add a _ctor version, but then resolve_nondeduced_context_or_error
    would need some changes too -- it'd have to check the result of a call
    to r_n_c for each element.

    gcc/cp/ChangeLog:

            PR c++/93107
            * pt.c (do_auto_deduction): Call resolve_nondeduced_context for
            the elements of a { } list.

    gcc/testsuite/ChangeLog:

            PR c++/93107
            * g++.dg/cpp0x/initlist-deduce3.C: New test.

    c++: list CTAD and resolve_nondeduced_context [PR106214]

    This extends the PR93107 fix, which made us do resolve_nondeduced_context
    on the elements of an initializer list during auto deduction, to happen for
    CTAD as well.

            PR c++/106214
            PR c++/93107

    gcc/cp/ChangeLog:

            * pt.cc (do_auto_deduction): Move up resolve_nondeduced_context
            calls to happen before do_class_deduction.  Add some
            error_mark_node tests.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1z/class-deduction114.C: New test.
