I'm sure PRE is only the enabler, not the culprit here, is it?

--- Comment #4 from Mikael Pettersson <mikpelinux at gmail dot com> ---
This wrong-code stopped occurring on trunk with r201251, and on 4.8 branch with
r202388 (PR57521).  The latter is a backport of trunk's r202019 (PR57521), and
applying that to trunk @ r201250 also fixes the wrong-code.
