* 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.
