From fe7a1f89fed8327056a1f79976eb6925bcca9d7c Mon Sep 17 00:00:00 2001 From: Myles Borins Date: Wed, 8 Nov 2017 13:06:37 +0100 Subject: [PATCH] deps: backport 3c8195d from V8 upstream MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Original commit message: Fix map constructor to correctly throw. We need to throw before rethrowing, otherwise the exception does not trigger a debugger event and is not reported if uncaught.
