The  following code  causes  an internal error and bus  error in cfront version
1.2.1 when I try to compile it. I believe that this is valid, although somewhat
unusual, C++ syntax. Is this acceptable code? This initialization works fine if
I change private data slot 'a' from a class_b& to something like an int.
