Hi Richard,

  Are you pointing to this line of test-case :

        size_t _sz = __builtin_object_size(dst, 1); 

 That we can't rely on __builtin_object_size this way.
 I am getting wrong size only if I use __restrict qualifier, otherwise it
calculate correct size.

 Also if we directly print the value of "__builtin_object_size(dst, 1)", then I
am getting correct size.

Kindly Confirm.

Thanks,
Ranjan Amit
