You've been advised before, but you really need to start reporting
these as bugs[*] if you actually care about them. llvm-dev is
basically a black-hole as far as bugs go: if no-one takes enough of an
interest to either fix or file a bug within a day or two, the issue
will be completely forgotten. The list is intended for discussion of
issues and future designs, not reporting them.

It seems you got lucky and someone did file at least one report from
one of these threads; you should expect that to become less frequent.
People are willing to assume the best of new contributors, but by the
time you reach a dozen threads without actually engaging with the
community's procedures that goodwill starts to look a bit threadbare.
