Steps to reproduce

esprima.parse('var AsyncGeneratorFunction = Object.getPrototypeOf(async function* () {}).constructor;')

Expected output

A valid syntax tree.

Actual output

Error: Line 1: Unexpected token *

Relevant references

This code is part of a test262 test that can be found at Since the test is not negative, I believe that the code is syntactically correct. It executes in Chrome.

Note: there seem to be 2854 non-negative test262 tests affected in the same way (Error: Unexpected token *).
