[Moved to DR at the April, 2013 meeting.]

Date: 2012-10-15.00:00:00

Proposed resolution (October, 2012):

Change 7.6.16 [expr.cond] paragraph 2 as follows:

If either the second or the third operand has type void , then the lvalue-to-rvalue (7.3.2 [conv.lval]), array-to-pointer (7.3.3 [conv.array]), and function-to-pointer (7.3.4 [conv.func]) standard conversions are performed on the second and third operands, and 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 and is a prvalue.

• ...

(This resolution also resolves issue 1560.)

The current wording of 7.6.16 [expr.cond] paragraph 2 says,

If either the second or the third operand has type void , then the lvalue-to-rvalue (7.3.2 [conv.lval]), array-to-pointer (7.3.3 [conv.array]), and function-to-pointer (7.3.4 [conv.func]) standard conversions are performed on the second and third operands, and one of the following shall hold:

• The second or the third operand (but not both) is a throw-expression (14.2 [except.throw]); the result is of the type of the other and is a prvalue.

• Both the second and the third operands have type void ; the result is of type void and is a prvalue. [Note: This includes the case where both operands are throw-expressions. —end note]

A parenthesized throw-expression is a primary-expression, not a throw-expression. Should a parenthesized throw-expression be considered a throw-expression for this purpose?
