--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
fre is able to handle this since GCC 7:
Setting value number of _1 to foo (changed)
Value numbering .MEM_7 stmt = _8 = _1 (&a);
Setting value number of .MEM_7 to .MEM_5 (changed)
Setting value number of _8 to _8 (changed)
Specifically r7-3276-g113d06a486475c which has a testcase which is very similar
to this.
So closing as fixed for GCC 7.
