Description:
https://bugs.mysql.com/bug.php?id=70236:

"[15 Oct 2013 17:56] Paul Dubois
Noted in 5.6.15, 5.7.3 changelog."

https://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-15.html:

"Incorrect reference counting in the range optimizer module resulted in potential for missing or duplicate rows in the query result set. (Bug #70236, Bug #17405466)"

This is incorrect - the bug has only been fixed in 5.7.3.

How to repeat:
$ git log --grep 17405466 --oneline 5.6
$ git log --grep 17405466 --oneline 5.7
