```
function opt(f) {
    try{
        return f(Uint8Array);
    }catch(e){
        print(e)
    }
}

print(opt(opt))
print(opt(opt))
```

run args:
WebKitBuild/Debug/bin/jsc --useConcurrentJIT=0 --jitPolicyScale=0.001 test.js

program output:
TypeError: calling Uint8Array constructor without new is invalid
undefined
0,0,0

expected output:
TypeError: calling Uint8Array constructor without new is invalid
undefined
TypeError: calling Uint8Array constructor without new is invalid
undefined

At the last call to the `opt` function, `f` is `UInt8Array`. The engine need to throw an exception instead of creating the array object.
