It seems to be the easiest way to get a char subscript :) It is actually from 
the bugreport. But I don't mind, I've changed the testcase a little: 

+extern volatile char bla;
+
 char foo (const char *s)
 {
-    return s [s ['\x80']];          // { dg-warning "array subscript" }
+    return s [bla];          // { dg-warning "array subscript" }
 }
