Am I missing something? It seems to me that any binaries that were compiled against the version of the header that didn't have the volatile in it may display incorrect behaviour with respect to accessing it, and on that basis it seems to me that it's reasonable to call it an ABI break (since the only way to fix the break is to recompile).

Hm. You might be right, though I'd not normally call 'earlier versions may have been misoptimized' to be something that constitutes an ABI break, at least not without investigation to see why the qualifier was added.
