--- Comment #9 from Jeffrey A. Law <law at redhat dot com> ---
The posted patch is just papering over the problem by changing the iteration
order of jump threads we examine. Since realization of some jump threads will
cause others to not be realized, changing the iteration order can cause
different jump threads to be realized.
As discussed PR72785, this is a kernel bug in that the kernel code assumes that
paths leading to a __builtin_object_size will not be duplicated/isolated.
