   1 """
   2 Test that parray of a struct with an embedded char array works.
   3 This was failing because the "live address" of the child elements
   4 was calculated incorrectly - as a offset from the pointer live
   5 address.  It only happened for char[] children because they used
   6 GetAddressOf which relies on the live address.
