###### Build steps
```sh
python ./tools/build.py --builddir=xxx --debug --clean --compile-flag=-fsanitize=address --compile-flag=-g --strip=off --lto=off --logging=on --line-info=on --error-message=on --stack-limit=20
```

###### Test case
```sh
//poc1.js

new s ( ) ; 
```
```sh
//poc2.js
const obj = { a : (o) = 1 };
var a = { a : (o) = 1 } = obj;

(class C2 { ["foo"] = 5; ["foo"] = {} + {} })((new (class o { ["foo"] = 5; [{ a : (o) = 1 } = obj] = {} + {} })).foo === 5);
print(o === 1);
```

###### Execution steps
```sh
./xxx/bin/jerry poc.js
