[PATCH] D8467: C++14: Disable sized deallocation by default due to ABI breakage

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Conceptually, this is (and will always be) a platform decision.  On Apple platforms, we have a formalized concept of deployment target, where specific minimum OS versions support sized deallocation and others do not.  On most other platforms, this is much vaguer — basically down to what C++ libraries you've got installed — and probably has to be controlled by a flag.  Enabling that flag by default on any particular Linux distribution release is something I'm not sure we can do unconditionally.
