            Bug ID: 86184
           Summary: Shall gcc support this feature?
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zhonghao at pku dot org.cn
  Target Milestone: ---

gcc++ produces errors when compiling the following code:

#include <stdio.h>

int main(int argc, char **argv) {
        printf("%p\n", (void *)0xdeadbeef ? : (void *)0xaaaaaa);
        return 0;
}


This code comes from a bug report of clang:
https://bugs.llvm.org/show_bug.cgi?id=7726

The programmers of clang discuss the code in details. They mentioned that gcc
does not accept the above code, but after all, they decide to implement the
feature to compile the code. 

Shall gcc also support this feature?
