c++/9687: The & operator does not accept parentheses on operand

[Wolfgang Bangerth]

Nathan,
you might be right, thanks for double-checking on me. I shouldn't dismiss 
reports late at night -- I misread this as the &(X::m) problem...

The relevant clause is 5.3.1.2, stating that the operand shall be an 
lvalue. This has nothing to do with the parenthesis, of course, so I guess 
you're right.

The present state is: 2.95--3.3 rejected the code. 3.4 now simply says
  warning: taking address of temporary
I guess this improvement is the effect of your patch. So in effect the bug 
has been fixed and the report can remain closed, right?

Thanks again for having an open eye,
  W.
