Indeed - easily determined by breaking down the expression.

So, who's gonna report it to gcc-bugs?  knu?...

int
main()
{
   unsigned char i = 127;
   char j;

   printf("%d\n", ((char)(i << 1)));
   j = ((char)(i << 1)) / 2;
   printf("%d\n", j);
   j = ((char)(i << 1));
   printf("%d\n", j / 2);
   return 0;
}
