#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.
