Consider the following script:

tick-1000
{
        i++;
        @[substr((i & 1) ? "Bryan is smart" : "he's not a dummy", 0,
            (i & 1) ? 8 : 18)] = count();
}

Here's the output:

# dtrace -s out.d
dtrace: script 'out.d' matched 1 probe
^C

  Bryan is                                                          2
  Bryan is a dummy                                                436
  he's not a dummy                                                437

Here's the offending code in dtrace.c:

                for (d[0] = '\0'; remaining > 0; remaining--) {
                        if ((d[i++] = dtrace_load8(s++ + index)) == '\0')
                                break;

                        if (i == size) {
                                d[i - 1] = '\0';
                                break;
                        }
                }

I would hasten to point out that "he's not a dummy" beat "Bryan is a dummy", albeit
in a down-to-the-wire squeaker.  Thank God for those two "Bryan is" write-ins!
