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