Basically a dup of bug 95159, I think.

It looks like the pending PR93383 patch fixes these testcases as well.

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.
