* 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.
