--- Comment #3 from Cimbali <me at cimba dot li> ---
Would it be possible to deactivate that optimization when shared is not the
default mapping? In practice here explicitly setting `shared(i)` has no effect
at all.

Note that I already recommended against such tricks in the discussion that
originated this bug:
