Thanks to *you* for doing all the work behind this!

I see, I suspected something was going on. It is very good to know the
reason behind it. When the feature is more stable, maybe it is a good
idea to add some of the known false positives/negatives to the GCC
docs (those that cannot be fixed), if any.

Thanks a lot -- following it.

I will! Sometimes I am not sure if reporting such things related to
new-ish features like this since they might be trivial, intended, or
impossible-to-fix; given how new and/or optimization-dependent they
are; and therefore wasting people's time :)

Cheers,
