Comment(by charris):

 I believe gcc got similar complaints when an Intel patch reversed the
 order of memcpy for (putative) efficiency reasons. It broke the Adobe
 flash plugin among other things.

 In place operations are always going to be tricky, what with views and
 all, and it isn't clear that the intended order can always be deduced. A
 warning message might be useful though.
