For loop leads to a crash

###### Version

chakra-1.11.24.0

###### Test case

```js
var x = 'a';
//large than 32 cause a crash
for (var i = 0; i < 32; i++) {
try { x = x + x; } catch (e) { }
}
print(x.length)
```

###### Execution steps

.ch Testcase.js

###### Output
```
Aborted (core dumped)
```

###### Description

This testcase caused a crash.
When we change the number of times in the for-loop to less than `32`, it will not cause a crash. It seems to be caused by the JIT Compiler.
