           Summary: The operator ? : doesn't work when Class::attr
           Product: gcc
           Version: 4.4.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: derzuomaia@gmail.com


Created attachment 21909
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=21909
contains 2 ii files.

The operator ? : doesn't work correctly, when is used a static class attribute
like Class::attr as the second param of the operator ?: . Exemple:

printf("type %d\n", num==0 ? Port::ASI_PORT : Port::IP_PORT);

G++ "thinks" that the first ':' is already the else ':'

Follows the output of the execution of:
bugg++$ g++ -v -Wall -save-temps main.cpp port.cpp

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2010-09-28 20:33:38 UTC ---
num==0 ? Port::ASI_PORT : Port::IP_PORT produces a lvalue so you need a
definition for those two.  See PR 44673.
