--- Comment #2 from Peter Cordes <peter at cordes dot ca> ---
The stray LEA bug seems to be fixed in current trunk (9.0.0 20180429), at least
for this testcase.  Gcc's stack-alignment strategy seems to be improved overall
(not copying the return address when not needed), so probably it's really
fixed.

It's still present in 7.3.
