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