Proposed resolution (February, 2014):

Change 7.6.16 [expr.cond] paragraph 2 as follows (this assumes the revised wording of the resolution of issue 1299 as the base text):

If either the second or the third operand has type void, one of the following shall hold:

  • The second or the third operand (but not both) is a (possibly parenthesized) throw-expression (14.2 [except.throw]); the result is of the type and value category of the other operand. The conditional-expression is a temporary expression if that operand is a temporary expression and is a bit-field if that operand is a bit-field.

  • ...

Presumably the result of something like

    b ? x : throw y

is a bit-field if x is, but the current wording does not say that.
