I can imagine. Or you can try to somehow "fix" the reduced test-case so that
it's valid again :)

c++: Alias template in pack expansion [PR99445]
In this testcase, iterative_hash_template_arg checks
alias_template_specialization_p to determine whether to treat a type as a
dependent alias, and structural_comptypes checks
dependent_alias_template_spec_p. Normally that difference isn't a problem
because canonicalizing template arguments strips non-dependent aliases, but
that wasn't happening for the pack expansion. Fixed thus.

c++: ICE with alias in pack expansion [PR103769]
This was breaking because when we stripped the 't' typedef in s<t<Args>...>
to be s<Args...>, the TYPE_MAIN_VARIANT of "Args..." was still
"t<Args>...", because type pack expansions are treated as types. Fixed by
using the right function to copy a "type".

* tree.cc (strip_typedefs): Use build_distinct_type_copy.
