It was originally sent to the sv-ec but it seems to belong in the sv-bc.

LRM 1800-2005 in chapter 4.11 - states:

"Members of unpacked structures containing a union as well as members of
packed structures shall not be assigned individual default member values."

There is no example  in LRM for above rule and I have doubts why it is
forbidden, and what in fact is forbidden?

Should below code fail on compilation because of this rule?

  module tb;

 struct { //structure containing a union
  bit a = 1;
  union { int c; int d; } n;
 } str1;

endmodule

????
