var x = function ( ) { } ?. ( ) . x ;
__________________________________________

Hello,

Executing the input.js using JSC, it is terminated normally.
However, it is expected to throw TypeError since `function ( ) { } ?. ( )` is `undefined`.

Running the input.js with JSC results in:

---
$ jsc input.js
// no error
---

while other engines behave like:

---
# V8
$ node input.js
input.js:1: TypeError: Cannot read properties of undefined (reading 'x')
var x = function ( ) { } ?. ( ) . x ;
                                ^
TypeError: Cannot read properties of undefined (reading 'x')
    at input.js:1:33

# GraalJS
$ js input.js
TypeError: Cannot read property 'x' of undefined
	at <js> :program(input.js:1:8-34)
