When the number of args requested is greater than the actual number of args supplied to the function call, the remainder of the args array should be filled in with `undefined` values. Because of this bug, the remainder of the array was left uninitialized, which could cause a crash. Refer to the documentation for the `argv` parameter at https://github.com/nodejs/node/blob/master/doc/api/n-api.md#napi_get_cb_info PR-URL: https://github.com/nodejs/node/pull/12863 Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Michael Dawson <michael_dawson@ca.ibm.com>
