Subject: Re: c++/3230: False warning for 'returning reference to temporary'

Synopsis: False warning for 'returning reference to temporary'

State-Changed-Why:
    This is not a bug in the compiler.  The standard (5.16) says that the result of your ?: expression is an rvalue, because the two options do not have the same type.  As a result, the return value binds to that rvalue, which is a local temporary.  The EDG compiler gives the same warning.
    
    You may feel that this is a bug in the standard, and I'd be inclined to agree.  But until the standard is fixed, the compiler will continue to work this way.  If you'd like to submit a defect report against the standard, the place for that is comp.std.c++.
