When we precompute something, we try to avoid allocating a new copy. That's important to
avoid many allocations each time we run Precompute - otherwise, each time we see a
br
we'd allocate a fresh one, and for its values. But we had a bug where we reused a RefFunc
as the value of a
br
without updating the type. It's actually tricky to reach a situation wherewe find a RefFunc to reuse and it is different from the actual one we want, but the fuzzer
found one.
Fixes the fuzz bug reported here: #6845 (comment)
