It's still >7MB long, so I'll stop reducing.

So I confirm it's a dup. Are you still interested in a reduced testcase?

--- Comment #15 from Avi Kivity ---
If I move the sub-expression that contains the std::initializer_list outside
co_await, the internal error is avoided.

Very likely it's a dup:
db::view::view_update_builder builder = co_await
db::view::make_view_update_builder(
base,
std::move(views),
flat_mutation_reader_from_mutations

The coroutine that breaks is
future<> table::generate_and_propagate_view_updates(const schema_ptr& base,
reader_permit permit,
std::vector&& views,
mutation&& m,
flat_mutation_

Ugh, I forgot g++ isn't the compiler proper and setting a breakpoint is going
to be tricky.

File is in https://scratch.scylladb.com/ice.cc (too large to upload to
bugzilla). I'll try to reduce it a little.
