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

<P>Presumably the result of something like</P>

<PRE>
    b ? x : throw y
</PRE>

<P>is a bit-field if <TT>x</TT> is, but the current wording does not
say that.</P>

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

<P>Change 7.6.16 [<A href="https://wg21.link/expr.cond#2">expr.cond</A>] paragraph 2 as follows (this assumes
the revised wording of the resolution of <A HREF="1299.html">issue 1299</A>
as the base text):</P>

<BLOCKQUOTE>

<P>If either the second or the third operand has type <TT>void</TT>, one of
the following shall hold:</P>

<UL>
<LI><P>The second or the third operand (but not both) is a (possibly
parenthesized) <I>throw-expression</I> (14.2 [<A href="https://wg21.link/except.throw">except.throw</A>]); the
result is of the type and value category of the other operand. The
<I>conditional-expression</I> is a temporary expression if that operand
is a temporary expression <INS>and is a bit-field if that operand is a
bit-field</INS>.</P></LI>

<LI><P>...</P></LI>
