description: Sliced strings
|

Rationale from https://github.com/tc39/test262/pull/999#discussion_r113807747
|
|
|
|
Since this test originates from V8, this targets V8's sliced strings, which are used for
|
|
substrings above a length of 13 characters. I wrote this test for exactly the reason
|
|
@littledan mentioned. That's why the variable name is called oob_subject. The underlying string
|
|
backing store extends beyond the actual boundary of the sliced string.

var oob_subject = "abcdefghijklmnabcdefghijklmn".slice(14);
|
|
assert.sameValue(oob_subject.match(/(?=(abcdefghijklmn))(?<=\1)a/i), null, "");
|
|
assert.sameValue(oob_subject.match(/(?=(abcdefghijklmn))(?<=\1)a/), null, "");
|
|
assert.sameValue("abcdefgabcdefg".slice(1).match(/(?=(abcdefg))(?<=\1)/), null, "");
