In cp_parser_constant_expression when we call cp_parser_assignment_expression
on the initializer, it returns
((char *) __builtin_memcpy ((char *) &str, (const char *) "Hello", 6);, 5)
As this is C++11, we call potential_rvalue_constant_expression which returns
true (the call in the COMPOUND_EXPR is builtin, and all its arguments are
pontential_rvalue_constant_expression arguments). I bet somewhere later on we
see that it is const and ignore the TREE_SIDE_EFFECTS initializer.
