// input.js
( function x ( [ x ] ) { } ( [ ] ) ) ;
__________________________________________
Hello,
Executing the input.js using JSC throws SyntaxError, but it is expected to be terminated normally.
Running the input.js with JSC results in:
---
$ jsc input.js
Exception: SyntaxError: Duplicate parameter 'x' not allowed in function with destructuring parameters.
at input.js:1
---
while other engines behave like:
---
# V8
$ node input.js
// no error
# GraalJS
$ js input.js
// no error
---
WebKit version: 615.1.10
