A problem in String length

Description

When I run the Test case , I find that jerryscript has no output. But if I set the loop number smaller than 174296, it can output correctly. Is it because that the number has reached to the maximum allowed String length in jerryscript? I wonder why the jerry outputs nothing.

Test case

var a = 'A';
var b = 'B';
for (var i = 0; i < 174296; i++) {
a = a + b;
}
print(a.length);

Output

Expected behavior

174297
