// 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)

WebKit version: 615.1.10
