     38 * SUMMARY: Testing script with at least 64K of different string literals
     39 * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
     40 *
     41 * Testing that script engine can handle scripts with at least 128K of different
     42 * string literals. The following will evaluate, via eval(), a script like this:
     43 *
     44 *     f('0')
     45 *     f('1')
     46 *     ...
     47 *     f('N - 1')
     48 *
     49 * where N is 0x20000
     50 *
