Proposed resolution (August, 2011):

Change the indicated bullet of 6.3 [basic.def.odr] paragraph 4 as follows:

  • an expression that is not a null pointer constant, and has type other than cv void*, is converted to the type pointer to T or reference to T using an implicit a standard conversion (Clause 7.3 [conv]), a dynamic_cast (7.6.1.7 [expr.dynamic.cast]) or a static_cast (7.6.1.9 [expr.static.cast]), or

The requirement in 6.3 [basic.def.odr] paragraph 4 that a type T must be complete if an expression is implicitly converted to a pointer to T or reference to T inadvertently applies to user-defined conversions, although it was intended only to refer to built-in conversions.
