<P>[Voted into WP at March 2004 meeting.]</P>

<P>14.2 [<A href="https://wg21.link/except.throw#3">except.throw</A>] paragraph 3 says that the type of a throw
expression shall not be
a pointer or reference to an incomplete type.  But an expression never
has reference type.</P>

<P><B>Proposed Resolution (October 2003):</B></P>

<P>Change the penultimate sentence of 14.2 [<A href="https://wg21.link/except.throw#3">except.throw</A>] paragraph 3
as follows:</P>
<BLOCKQUOTE>
The type of the <I>throw-expression</I> shall not be an
incomplete type, or a pointer <DEL>or reference</DEL>
to an incomplete type <INS>other than (possibly cv-qualified)
<TT>void</TT></INS><DEL>, other than <TT>void*</TT>,
<TT>const void*</TT>, <TT>volatile void*</TT>, or
<TT>const volatile void*</TT></DEL>.
</BLOCKQUOTE>
