Just encountered this bug myself, with trunk gcc (11.0.1 20210321
(experimental)).

See godbolt: https://godbolt.org/z/TxW137Whh

    c++: do_class_deduction and dependent init [PR93383]

    Here we're crashing during CTAD with a dependent initializer (performed
    from convert_template_argument) because one of the initializer's
    elements has an empty TREE_TYPE, which ends up making resolve_args
    unhappy.

    Besides the case where we're initializing one template placeholder
    from another, which is already specifically handled earlier in
    do_class_deduction, it seems we can't in general correctly resolve a
    template placeholder using a dependent initializer, so this patch makes
    the function just punt until instantiation time instead.
