Bug 247434 – Invalid call chained with optional access

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: JavaScriptCore

[Kanguk Lee]

// input.js
( { } . x ( ) ?. x ) ;
__________________

Hello,

Executing the input.js using JSC, it is terminated normally.
However, it is expected to throw TypeError since `{ } . x` is not a function.

Running the input.js with JSC gives

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

while other engines behave like

---
# V8
$ node input.js
input.js:1: TypeError: {}.x is not a function
( { } . x ( ) ?. x ) ;
        ^
TypeError: {}.x is not a function
    at input.js:1:9

# GraalJS
$ js input.js
TypeError: (intermediate value).x is not a function
	at <js> :program(input.js:1:2-12)
