Summary: The operator ? : doesn't work when Class::attr
Product: gcc
Version: 4.4.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: derzuom...@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
Using built-in specs.
