           Summary: Incorrect scalar increment result
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: schaub.johan...@googlemail.com


The following test-case should output "2 3", but GCC outputs "1 2":

#include <stdio.h>

int arr[] = {1,2,3,4};
int count = 0;

int incr(){
 return ++count;
}

int main(){  
   arr[count++]=incr();
   printf("%d %d",count,arr[count]);    
   return 0;
}

(it may not be obvious; see

Clang correctly handles this case.
