            Bug ID: 124576
           Summary: multiple evaluation of typeof arguments
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: uecker at gcc dot gnu.org
  Target Milestone: ---

In the following example, j++ but not i++ is evaluated three times which is
wrong (thanks to Hsiang-Ying Fu)

int main() {
    int i = 0;
    int j = 0;
    typeof((typeof(int[i++])*)(j++, 0)) a, b, c;
    return j;
}
