#3395: Assignment to optional is not possible if operator& is overriden
---------------------------------+------------------------------------------
 Reporter:  andysem              |       Owner:  fcacciola
     Type:  Bugs                 |      Status:  new      
Milestone:  Boost 1.41.0         |   Component:  optional 
  Version:  Boost 1.40.0         |    Severity:  Problem  
 Keywords:  optional assignment  |  
---------------------------------+------------------------------------------
 The assignment operator for optional< T > uses T::operator& to dispatch
 the call between assign_expr functions. This dispatch breaks if the
 T::operator& returns something else than T*. This is the case with ATL
 types, such as CComBSTR.

 The suggested fix is to replace call to operator& with addressof. Please,
 find the attached patch against the 1.40 release.
