I agree that the obvious special cases are access through char*, arrays of characters, and placement new. But, I'm afraid that there are lots of other allocation functions out there that are not spelled "operator new", and requiring decoration for them isn't something that (as far as I know) other compilers require. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29286
