22 from "a". This means that an explicit read barrier is required, for example
64 barrier();
68 barrier();

143 tempting to add a barrier(), but this does not help. The conditional
144 is gone, and the barrier won't bring it back. Therefore, if you need
230 barrier() at beginning and end of each leg of the "if" statement
