--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
build_trivial_dtor_call has:
if (INDIRECT_TYPE_P (TREE_TYPE (instance)))
{
if (VOID_TYPE_P (TREE_TYPE (TREE_TYPE (instance))))
goto no_clobber;
instance = cp_build_fold_indirect_ref (instance);
}
so, either we adjust the caller such that for TYPE_PTR_P types it passes an
address of the instance rather than the instance itself, or we add an argument
(perhaps defaulted bool) to build_trivial_dtor_call that inhibits this behavior
for TYPE_PTR_P, or drop this if completely and adjust any caller that calls it
with a pointer or reference and expects it to destruct what it points to rather
than itself.
