    1.13 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
    1.14 + *
    1.15 + * Testing that script engine can handle scripts with at least 64K of different
    1.16 + * string literals. The following will evaluate, via eval(), a script like this:
    1.17 + *
    1.18 + *     f('0')
    1.19 + *     f('1')
    1.20 + *     ...
    1.21 + *     f('N - 1')
    1.22 + *
    1.23 + * where N is 0xFFFE
    1.24 + *
