AFAIK, the problem is actually within emplace, that tries to call 
opAssign when it should really be just (post)blitting. This is 
just one of the many emplace-related bugs.

I have an open pull for fixing emplace that should fix this. I'll 
add your snippet to its unittests to confirm that it also fixes 
this issue.
