  38 * SUMMARY: Don't crash on invalid regexp literals /  \\/  /
  39 *
  40 * See http://bugzilla.mozilla.org/show_bug.cgi?id=122076
  41 * The function checkURL() below sometimes caused a compile-time error:
  42 *
  43 *         SyntaxError: unterminated parenthetical (:
  44 *
  45 * However, sometimes it would cause a crash instead. The presence of
  46 * other functions below is merely fodder to help provoke the crash.
  47 * The constant |STRESS| is number of times we'll try to crash on this.
  48 *
