274. Cv-qualification and char-alias access to out-of-lifetime objects

[Voted into WP at April 2003 meeting.]

The wording in 6.8.4 [basic.life] paragraph 6 allows anlvalue designating an out-of-lifetime object to be used as theoperand of astatic_cast only if the conversion isultimately to "char&" or "unsigned char&".This description excludes the possibility of using a cv-qualifiedversion of these types for no apparent reason.

Notes on 04/01 meeting:

The wording should be changed to allow cv-qualified chartypes.

Proposed resolution (04/01):

In 6.8.4 [basic.life] paragraph 6 change the third bullet:

• the lvalue is used as the operand of astatic_cast(7.6.1.9 [expr.static.cast])(except when the conversion is ultimately tochar& orunsignedchar&), or

• the lvalue is used as the operand of astatic_cast(7.6.1.9 [expr.static.cast])except when the conversion is ultimately tocv char& orcv unsigned char&, or
