Steps to reproduce:
// This is a simplify case, not the real use case.
var regexp = /((?:.)*)/;
var str = '';
// Build a very long string
while (str.length < 999997) str = str + 'A';
// Try to make it match the regexp
var match = str.match(regexp);
console.log("Match for 999997 chars : ", match);
str = str + 'A';
match = str.match(regexp);
console.log("Match for 999998 chars : ", match);
Actual results:
Match for 999997 chars : 2
Match for 999998 chars : null
Expected results:
Match for 999997 chars : 2
Match for 999998 chars : 2
