Yes, I thought that the 'break' keyword wasn't used in if clauses. I took it to mean a problem with line ending resulting in the premature closure of the switch block. Anyone any ideas as to possible syntax?

It would make sense if the author had meant do clause instead of if clause.

Something like that:

  do {
    switch (bleh) {
      case MEH:
        if (derp) {
          break; /* supposed exit the do..while loop early...
                    except it only exits the switch statement */
        }
        [...]
        break; /* usually there's a break at the end of each
                  case statement, but the programmer might
                  not have seen it if it's far away */
    [...]
    }
    fun_stuff(); /* not supposed to be called when
                    bleh == MEH and derp is non-null */
  } while (quux);
