michael@0:  * SUMMARY: Testing script with at least 64K of different string literals
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
michael@0:  *
michael@0:  * Testing that script engine can handle scripts with at least 64K of different
michael@0:  * string literals. The following will evaluate, via eval(), a script like this:
michael@0:  *
michael@0:  *     f('0')
michael@0:  *     f('1')
michael@0:  *     ...
michael@0:  *     f('N - 1')
michael@0:  *
michael@0:  * where N is 0xFFFE
michael@0:  *
