>Description:
the prefix increment operator is not correctly evaluated in the following code:

int a[8];
int i = 4;
a[i] = ++i;

the last line is evaluated as 
a[4] = 5;
instead of 
a[5] = 5;
>How-To-Repeat:
void test(void)
{
int a[8] = {0,0,0,0,0,0,0,0};
int i = 4;
a[i] = ++i;
printf("\na[4] = %d\na[5] = %d\n", a[4], a[5]);
}
