[PATCH] D17746: Fix PR26741 -- __builtin_object_size is not consistently conservative with C++ inheritance

[Richard Smith via cfe-commits]

rsmith added a comment.

Can you explain a bit more about the problem? It seems to me that if I have:

  struct Base {
    char k[1];
  };
  struct Derived : Base {};

... then the 'k' subobject of a `Derived` object is known to be exactly 1 byte long -- it doesn't seem obviously appropriate for our flexible-sized trailing array support to cover this case.
