Confirmed. We don't even give a warning about taking the 
address of a temporary :-( 
 
This is what I get from icc: 
g/x> icc -Xc -ansi -c x.cc 
x.cc(9): warning #592: variable "a" is used before its value is set 
      return a; 
             ^ 
 
x.cc(14): error: expression must be an lvalue or a function designator 
      int* p = &f().a;   // should reject as rvalue.field is still an rvalue 
                ^ 
 
compilation aborted for x.cc (code 2)
