Hi Jakub,

I tried to reduce the code as much as possible before reporting, which is why
the example has the "this != &o" check in the copy constructor.

The original code where I saw this problem had the "this != &o" check in the
assignment operator, and the copy constructor called the assignment operator.
In the reported version, I manually inlined the assignment operator.

I think the original code is also silly, but not as clearly wrong as the
pointer check in the copy constructor.


Note that the warning happens on a completely different class "Normal" from the
silly code "Weirdo", so I'd consider that a bug in addition to the diagnostic
containing 'target_mem_ref' and 'dump_expr<expression error>'.
