説明

Hi everyone, I found a case of redeclaration of a generator function inside a block definition.

version: 1.11.19 OS: Linux Ubuntu 19.10 x64

steps to reproduce:

{ function* f() { yield 1 } function f() { print(2) } } f() Actual results: 2

Expected results: SyntaxError: Identifier 'f' has already been declared

V8, SpiderMonkey works as expected.
