<P>[Moved to DR at the November, 2014 meeting.]</P>



<P>It is unspecified if an implicitly-defined copy assignment operator
directly invokes the copy assignment operators of virtual bases.  The
<I>exception-specification</I> of such a copy assignment operator is
thus also unspecified.  The specification in 14.5 [<A href="https://wg21.link/except.spec#14">except.spec</A>] paragraph 14
should explicitly include the exceptions from the copy
assignment operators of virtual base classes, regardless of whether the
implicit definition actually invokes the virtual base assignment operators
or not.</P>

<P><B>Proposed resolution (June, 2014):</B></P>

<P>This issue is resolved by the resolution of
<A HREF="1351.html">issue 1351</A>.</P>
