--- Comment #5 from Jeffrey A. Law <law at redhat dot com> ---
-Os was changed to throttle jump threading as the block copying can result in
larger code.  With jump threading throttled, unexecutable paths are left in the
CFG which reduces the preciseness of warnings such as Wuninitialized.

Tracking via BZ 42145, but not expecting to fix it anytime soon.
